Forge：2847
Mod version：1.10.22
Server：CatServer-universal

The reason is unknown, the console appears repeatedly
Sorry, my English is not good. I'm Chinese

Same issue same Mod version. In our case its the Amara Constellation firing this issue on player join , claiming he is hit be a wooden spike and force disconnets him after several error repeats. The general issue however is the same. Prior to that but maybe unrelated is a error that occured calling it.unimi.dsi.fastutil.chars.AbstractChar2ObjectFunction.put(AbstractChar2ObjectFunction.java:119) ~[fastutil-7.1.0.jar:?] wich resulted in a Unsupported Exception.

Server log upload for review would be appreciated.

Sorry, the log is gone. I will upload the full log when it appears again

here the server log https://hastebin.com/piciculoru.shell

and the corresponding client crash log . https://hastebin.com/zawuhadali.rb

The disc/error server side and the crash client side are pretty close on the time scale (difference in hours are related to time zones), still both might be unrelated to each other.

The report you provided was not AstralSorcery's fault

Please remove VanillaFix

Thanks for the help that apperently fixed it for the User ^^

Uhm, i guess this is resolved then?

Mostly i guess, it seems to be still a mod interaction issue at least in some corner cases,other user didnt report any issues and only in this case of him trying to connect the console fired null pointer exceptions like crazy.
