Related Mods and their Versions

I am running version "6.1.0 Release" of the Valhelsia 6 mod-pack. If you'd like you can check the Valhelsia 6 list for all versions of each mod, but I'm just reporting this in case someone sees an obvious flaw. I'm very thankful for the Minecolonies team. I will also let the Valhelsia staff know about the bug so they can update to the latest version of Minecolonies. :)

Reproduction Steps

This issue happened suddenly and without explanation. The only cause I can see is increasing my minimum simulation distance using DynView. I changed the simulation distance over a week ago and the bug didn't happen until maybe yesterday or the day before. DynView changes the simulation distance dynamically based on server performance, and I never noticed this bug before I
increased the minimum simulation distance, so that's why I say it might be the cause.

Anything else?

Thank you for your hard work on the Minecolonies mod. It's one of my favorites. If you need me to do further testing I can, but like I said earlier I'm not the mod-pack creator so I will need to let the Valhelsia 6 mod-pack staff know about the bug and have them update the Minecolonies mod and their mod-pack so that all the players on my server run the same version.

I could check to see if updating the mod fixes the bug, but I'd have to make a duplicate of my MC server which is a huge hassle at the moment. I hope that you can find the cause from my attached logs.

• Add a thumbs-up to the bug report if you are also affected. This helps the bug report become more visible to the team and doesn't clutter the comments.
• Add a comment if you have any insights or background information that isn't already part of the conversation.

Because you are on such an outdated version of the mod, you're probably going to find that it has already been fixed in the many versions since then =)

Please reopen if it persists on the newest

I think I've solved the issue and found the cause of the bug.

I switched my builders' "Construction Strategy" to "Inward Circle Height 2" and that appears to cause them to bug out. Switching them back to "Default" and cancelling their build-in-progress fixed it.
