WorldEdit //regen issues

[markhughes]

Hello! Using WorldEdit (and FAWE - so this may be an issue with just FAWE or worldedit) and Orebfuscator and the //regen command causes the blocks to become random ores/gravel etc - or huge portions of coal.

Unfortunately no screenshot here yet (whenever it happened I was on a live server so I had to quickly unload orebfuscator and redo it), but I will undertake some further testing soon for you. Is there anything I should do while testing further to provide further useful information?

• PaperSpigot b832
• WorldEdit 6.1.4 3594
• FAWE 3.5.1
• Orebfuscator 4.1.4

This bug was also present in the previous version. But I found it doesn't occur when I take off Orebfuscator

---

Edit 1: Testing

Versions:
Plugins (5): FastAsyncWorldEdit, Vault, ProtocolLib, WorldEdit, Orebfuscator4

• FastAsyncWorldEdit version 16.08.27-5baa99e-243
• Vault version 1.5.6-b49
• ProtocolLib version 4.0.2-SNAPSHOT-b293
• WorldEdit version 6.1.3;7a097ca
• Orebfuscator4 version 4.1.4

Start to finish log: http://pastebin.com/nKZ7Vc04

If I take off Orebfuscator this no longer occurs - the above example is a much nicer result than usual.

Disabling Orebfuscator fixes the issue.

However, disabling FastAsyncWorldEdit also fixes the issue. Perhaps @boy0001 would like to take a look too?

[markhughes]

I have updated my ticket with more information!

Hello,

Thanks for problem description.
Is it possible for you to prepare "server folder" and provide me it with steps I have to do to see the problem?

[markhughes]

I have attached the plugins folder.

To reproduce:

• Use //pos1 to select your location
• Move about 2-3 chunks diagonally and use //pos2 to create a square
• Use //expand vert
• Use //regen

plugins.zip

[Aleksey-Terzi]

Thanks, I've reproduced problem.
I will try to find the reason and fix (if issue in Orebfuscator's side)

[markhughes]

Opened the issue @ boy0001/FastAsyncWorldedit#273 as well

[RoboMWM]

I conclude that this isn't an issue: comment on the other ticket

@markehme

1. Just to confirm - Orebfuscator is not changing real map data, it is changing only what is sent to the client. Clear cache, relog client - and you will see "not corrupted" map.

2. Problem happened because of "//regen" command with FAWE is sending fake block ID's. Client just converting such blocks to AIR, but Orebfuscator no.

Therefore I'm considering this is bug on FAWE side, but I anyway applied change to convert "fake blocks" to AIR.

This should fix the problem you mentioned.

You can wait until new release or could compile plugin by your self from DevotedMC fork.

Thanks @Aleksey-Terzi, it's really scary to players when you go to regenerate something and it turns into a cluster of ores!

[markhughes]

Just confirming. The issue appears to be fixed, awesome!

Thanks - IOU a beer
