[Server] Changing levels to nt_shrine_ctg causes segfault

Description

Changing levels on a dedicated linux server to nt_shrine_ctg causes a segfault. I've attached a crash dump for analysis. It likely happens with maps with displacements, but I cannot confirm that.

To Reproduce

1. Start server on map that doesn't crash upon launch.
2. Change map to nt_shrine_ctg (or anything presumably with displacements [unverified])
3. Server segfaults immediately.

Expected behavior

Server should be able to host nt_shrine_ctg without crashing.

Actual behavior

Server segfaults and reboots.

We might want to collect a list of maps that cause segfaulting, #592 is related.

[AdamTadeusz]

#28 is probably even more related

note that there was research into the topic in the discord, additionally there are "fixed" versions for bullet and shrine available (but their displacements are wacky, but seems to have fixed the crash)

sth sth displacements power of 2

Would it be worthwhile to convert all of the "Map X crashes" issues into this meta issue: NeotokyoRebuild/neoAssets#1 ? Because trying to forward-port the old maps to be fully compatible might not be a worthwhile venture, if we can simply solve it by recompiling.
