Crash in Rift

[Fluboxer]

So I got recent beta from Actions tab and it seems to crash me in Rift when I fight vampire slayer?

Thing: crash-2023-07-28_14.55.29-client.txt

It's because hypixel send wrong base64 for skins

It happen for Scion in Private island and on Vampling or smth like that in the château in the rift

They also send a wrong base64 for the head texture of the snail pet

[Fluboxer]

Yes, however, my problem is not spam in console and/or lack of skin on few things. I included it just in case as it happened right before "[Render thread/ERROR]: Unreported exception thrown!"

My problem is that it crashed when you fight vampire slayer. I did few attempts and can't see any correlation as it crashes at different phases

Make sure you are running on the latest build and try to disable features like the thing to remove stuff in log and vampire features until it doesn't crash anymore

[Fluboxer]

Tested it without skyblocker - it works

Tested it with only popular FPS mods - it works
Tested it with full kit - also works

then I noticed that I had VPN on. Turned it off and it happened again? ...
don't we all love bugs like this? :)

and no, it was functioning properly before. I will do few more tests and proceed to update this issue

[Fluboxer]

Update: after "well it seems to do something with connection" answer was quite obvious: it is krypton
I probably accidentally enabled it first time and "testing with full kit" involved enabling it too

this is quite dumb - both me and situation as a whole. I will make few more tests just in case before closing it

[Fluboxer]

There is more to this clownfiesta

Krypton's removal haven't solved the issue, however, looking at recently changed mods I noticed something
Reason why I went here to post issue is because it started to happen when I updated skyblocker. But with skyblocker I also updated Fabric API as it demanded newer version
(context - I don't play rift much so there was 1-2 week gap between good non-crashed sessions and this)

Combo of "skyblocker-1.10.0-beta-97b049f+1.20.jar" (random few weeks old skyblocker from actions tab) and FabricAPI 0.85.0 was able to persist for whole session. For context - while I were checking mods and changing conditions in attempt to catch whatever the hell is that, it were crashing me instantly/in first minutes of existing at vampire slayer château. It happens only at vampire slayer place - you can do whatever in other rift places

Just like with krypton case, it may be pure luck so I will make more tests before heading to FabricAPI's github
UPD: may as well try newest skyblocker version in case try catch will solve that
UPD2: newest version didn't help 💀

[Fluboxer]

Another update on this stupid issue in case someone will ever get it too

No, fabric API also weren't the cause - and at this point I decided to just brute-force mods until I either end up crashing in vanilla or find that sneaky mod that were breaking all that stuff

And after removal of ImmediatelyFast I was able to grind some vamps without crashes. In fact, I managed to grind whole timecharm without crashes on profile where I took down this mod

Maybe it was some weird interaction. Maybe IF wasn't guilty for this and I just got very very lucky - who knows, but if something that crashes 70% of the time in first second suddenly can persist for like 4-5 sessions - I would consider it working properly

[Julienraptor01]

i don't think the issue was caused by IF as i can't reproduce, but talking with IF's dev, he told me that the culprit was maybe dashloader
you should try to put back IF and remove dashloader
seems like i was mistaken and lucky, see below
