• Can you reproduce this issue with relevant mods only?: yes/no
  Yes and No

Kind of a strange answer. It works just fine in single player on Windows, but on my Linux server, after editing the lines for drop type, it appends 'true' or 'e' at line 19 and creates a .bak file. Then the server crashes.

try deleting the config file

do you mean you were editing config while game is running?

No, I stopped the server and edited the config. Upon next two launches, it appends the e, server stopped again, and 3rd launch, it crashes with above crash log

Right, I did that, it goes back to default, and everything works just fine, but changing it once again to NO_DROPS on multiplayer line puts the 'e' back, or puts in 'true' on line 19

edit: wrong log

I should mention I did not have this issue on forge 36.1.10

We;ve decided to keep it as default and use the drops for Botania, so no worries, I can close this, likely a localized issue anyway ^-^
