Crash Instead of showing a Missing Mods Screen

[WenXin20]

Streams v0.3
Farseek v2.0
Forge 2151
It crashes on game launch.
Crash Log

[Edit] 12/15/16
It happened when I deleted Forestry but forgot to delete the More Bees Mod.
So it seems like Streams is causing this crash instead of going to the Missing Mods warning page with the dirt background. After removing Streams and Farseek, instead of crashing it shows the Missing Mods warning.

I'm experiencing the same crash with the new Streams/Farseek. Not much to add other than it's not an isolated incident.

[ghost]

I had the same crash and found out it was caused by BiomePaintTools.

[WesCook]

I do not have BiomePaintTools installed, myself.

[ghost]

Ok, but WenXin20 does and I suggest to look there first. I can confirm the crash was gone after removing BPT from my modpack which has 71 other mods in it. Without BPT, it runs just fine. Maybe it's caused by several mods?

[WenXin20]

I removed Biome Paint Tools Mod and now it works for me too.

[WesCook]

Interesting, I may be the exception then. I'll need to do some further testing to see if another mod is causing an issue here.

---

edit: I placed it back in my modpack environment and things seem to be working smoothly now... I'm not sure what's changed. Perhaps one of the mods I've discarded in the mean time. Sorry for the confusion!

I figured out I forgot the Hammer Core mod. It's listed as a dependency but I missed it.
I don't know why Streams throws this error - a had the same as WenXin20: "java.lang.NoClassDefFoundError: streams/client/package" - but after putting Hammer Core in the mods folder, the crash isn't happening anymore.

[WenXin20]

That's odd, I already have the hammer core mod.

This isn't a bug with any mod, it is a forge bug. This heppens if you have duplicated mods or missing mods. If you can show me your log file of the start, I've be able to tell you what does break it

[WenXin20]

I don't think I have any duplitcated or missing mods, but here is my log file:
log

[canitzp]

this isn't the complete log file

[WenXin20]

Is the fml-client-latest log the one you wanted? Because that is what the log is, the game just named loaded past the construction stage before it crashed

[canitzp]

the log you posted is cut off, for me the last 1000 lines are important, they are enough, cause some uploader haven't infinite words/lines

[WenXin20]

Are you sure it's cut off, for me it's not, but at the top of the Web page it says that the file has been truncated, but that link leads to the full file: https://gist.githubusercontent.com/WenXin20/35c17c368cc9f196adba808b043b7b75/raw/995b291f222e0fbbf83776947d83b9ac0cea976f/Streams%2520Mod%2520Crash%2520w.%2520Biome%2520Paint%2520Tools%2520Latest%2520Log%2520

[canitzp]

here is your mistake. :03:56] [Client thread/ERROR] [FML/]: net.minecraftforge.fml.common.MissingModsException: Mod chickens (Chickens) requires [Forge@[12.18.3.2185,)]

[WenXin20]

Ok, thanks, I'll try updating forge to see if that fixes it tonight

[WenXin20]

Ok, that fixed it. Funny thing was that I had already updated forge, but I had disabled the streams mod before I had updated forge. :D

[WenXin20]

Turns out that wasn't a real fix. I got the crash again, but this time it happened when I deleted Forestry but forgot to delete the More Bees Mod.
So it seems like Streams is causing this crash instead of going to the Missing Mods warning page with the dirt background. After removing Streams and Farseek, instead of crashing it shows the Missing Mods warning.

[canitzp]

there is maybe a wrong class transforming that causes forge to load a non existing class, cause streams isn't loaded at this time, but it is scala code, so I have my problems to read it.

[delvr]

Thanks WenXin20, WesCook and canitzp for your help in investigating this so far. Sorry for the delay on my end, I'll look deeper into this issue and get back to you.

[canitzp]

No problem, I like to investigate such strange things

[WenXin20]

Cool, thanks for looking into it.

[WesCook]

What I've found of this error is that it shows up whenever there's a problem with loading Forge mods. For instance, I accidentally had two versions of a mod installed. Instead of throwing the usual Forge "duplicate mod ID" screen, it showed the "NoClassDefFoundError: streams/client/package" error. Once I removed Streams/Farseek, I got the standard Forge error.

So I think in many cases Streams is being blamed where other mods are at fault; but at the same time, Streams is doing something to break the Forge error reporting.

[delvr]

Fixed in Farseek v.2.1.

[WesCook]

Fix works great. Thanks for the update!
