Thank you for the report! I will investigate the issue.

I tried to reproduce this issue but cant. Whole Gaia II fight comes normal, succesfully killed it and it had drop.

I found that your crash happens there in the code of generating invisible Land Mines. For some reason, Botania cant find any players around.

But when I fought Gaia II, there was this mines and everything was ok.

Maybe I need more tests on server.

yes the crash did happened in a server.
I did not try the fight on the 1.35 so maybe it is fixed. Will try and come back with the result.
