We are using Uber Crafter on our three servers and we have an issue with UC wooden foundation and Raft Extended mod. When i use generic foundation or S+ one, we can build the raft as intended but there are limitation (like wall size) that we want to use UC like for all our other buildings. When we place wooden foundation (or stone or metal) on raft, something goew rong and we can't extend. If we do using UC foundation ability to snap to a previous foundation, at one moment everything collapse or stick to the nearest ground.

1) What item are you having issues with?
Using UC and Raft Ectender
2) Are you single player or server?
Three servers (2 Nitrado based and on BlackBox)
3) What map are you using?
2 x TheIsland and 1 x Center
4) Is it a recurring issue or is it a one off?
Recurring
5) Have you tried deleting the mod folder?
we have even wiped the server once, made multiple deletion and reinstallation, even with only those two mods installed, but it comes back.

Could you please plan to have a look and see if you can find why it acts like this. Take your time, it is just that we would really appreciate if you could find the reason behind it. The size of your wall is helping tremendously to fix some collision issues and allow to make nice decorations, we would like to be able to use it on Extended raft.
