Same thing here, never happened before.

I have the same thing. Manually rolled the mod back to 2.0.8 and the issue remains. Seems to be the object itself rather than the specific action. It will break when changing what is attached to it, when you try to remove it manually or with a bot, when you destroy it, when you try to upgrade items attached to it....

Yep, but only a single entity of belt balancer has this problem, everything else is doing fine... i bet this will not be so easy to debug.

Also got an error like this. Can't remove the balancer itself or the connected belt/tunnel manually or with bots.
