a few friends of mine and me are playing on a server thats hosted by server.pro. we played for over 50h on this world, spent a lot of time building everything in it and suddenly the server crashes in direct response to one of my mates pressing the r key in their inventory. i am not sure if thats associated with the crash log, but i really could not extract any information out of this log. please help, we really do not want to lose this world. thanks in advance if any more information is needed please let me know. edit: maybe i should mention its modded in 1.12.2 with the latest forge version (14.23.5.2854) latest (1).log
