Hm, yeah sounds like these'd be Cauldron issues. Was supposedly an Opis update in the works I think to fix some issues, but no sign of it yet.
Fastcraft dosnt work with cauldron. thats normal.
We dont need/use opis so its removed but it woud work with 1388.
Noticed this occasionally too. I'm still looking for a mod that has customizable fuels for a good working chunkloader that isn't part of a giant mod (like railcraft).
I woud love to see chicken chunks but there arnt many options with fuel.
This is very strange, and I'm wondering if its a cauldron issue or a compact machine issue, but I'm thinking it MIGHT be the latter due to other reports over the last few versions.
I cant find any report about thise issue and problem is i cant reproduse it.
It hapens to 4 players incuding me. No serverlags/errores at this moments, no specific order of old rooms taking over. Its all random what i can see.
Destroying all machines linkt to a "corrupted" room doesnt help either.
As soon as the chunk get loaded it starts with the errore.
This looks to be partially a cauldron issue, but partially an issue with current HQM thats being worked on in the massive rewrite/update.
Not mutch i can do right now. We will see what happens with the next update.
Newest cauldron version dosnt help. We are now back to 1388.
