"This block is missing its respective building, try restarting or loading a backup"

[NKPoulsen]

Is there an existing issue for this?

• I have searched the existing issues.

Are you using the latest MineColonies Version?

• I am running the latest beta/release version of MineColonies for my Minecraft version.
  I am also running the latest versions of other mods that are part of my problem.

Did you check on the Wiki? or ask on Discord?

• I checked the MineColonies Wiki and made sure my issue is not covered there. Or I was sent from discord to open an issue here.

What were you playing at the time? Were you able to reproduce it in both settings?

• Single Player
• Multi Player

Minecraft Version

1.20

MineColonies Version

1.1.846-1.21.1-snapshot

Related Mods and their Versions

All mods are as per ATM10 version 2.22, installed via Curseforge.

Current Behavior

Within minutes of starting world, huts, buildings etc stop being interactable and instead give the "This block is missing its respective building, try restarting or loading a backup" error.

Teleporting away and returning fixes this temporarily.
Restarting client fixes this temporarily.
Sometimes waiting a few seconds fixes this as well.
Installing new client version of modpack fixed this for about an hour.

Expected Behavior

when interacting with building block, normal ui should open.

Reproduction Steps

We are unsure how to reproduce. It 'just happens' after a very short while.
Log has been provided including a crash report, as the game crashed just after the issue happened.

Update: Tried the following:
disabling shader mod (iris)
re-installing modpack clientside and then disabling shader mod (iris)

Might be linked to jei, but we have no clue.

Can we have the client log too?

Can we have the client log too?

Hmm, it should be the latest.log, debug.log and crash.log that has been linked. Could you tell me more about what the client log is?
Might also have linked it incorrectly - it's my first time using gist.

Additions to gameplay:
builderbuildblockdelay = 5
blockminingdelaymodifier = 50

How did you change these? Those settings don't exist any more do they?

Had a look in the configs from FTB Inferno and manually input them to the server config, thinking they would work. In theory we don't know if they do, but it feels like it. I wouldn't mind if it's just placebo haha
