Error in console / Buggy items

[Maingron]

I'm getting this error in my console frequently. Also the items are bugging often when using the compression table. I suspect it's the same error.

Thanks for the report! I will look in to this.

When you get a buggy item, what is wrong with the item? Knowing that might help narrow down where I look when bug hunting

[Maingron]

The item stays what it's supposed to be (at least I think), but it's really exhausting to work with. The GUI may reset to the previous state, for example (before you started rearranging or shifting items). I'll see if I can provide visualisation

[Foxcapades]

A visual would be perfect
