as of today, this should have some workaround implemented.

Small update on this case.
most common issues should self-heal, however in case of certain mod-data corruption, manual intervention will be needed.
Mod will now log location of those occurrences in above message - last 3 digits are x,y,z.

Find that square (use https://map.projectzomboid.com/ if needed, debug/admin mode and teleport to said coordinates, etc.)
- if on that square is any object, like barrel, delete it
- place pipe on this square
- wait in-game 10 mins and it would trigger above error and it should pass and delete that square (and all mod data related to it)
- pipe will be gone from that square, if so, place barrel again
- after another 10 in game minutes, there should be no error logged.
