Sorry but what do you expect from me in this situation with this little information?
I just warped to the OX map (game99) and even started an event, did not crash for me. Warped to another game99 map (gm_guild_build), did not crash.
I don't know when it crash for you, what do you do when it crash, or is it crash because of a modification you made.
To find out or at least to have a clue why it crashed for you, do a gdb and copy the output of bt and / or bt full here.
But if you see it's coming from a new system then please kindly open a new topic in q&a.
