Not sure what this is, but thought I should forward to you...

Crashy crash

Hmm. This is something that happens when a part is missing. Is this with modified assets?

Basically it is trying to get a floor part of a building and the building returns a part that doesn't exist

Ah - I see. I am playing with modified buildings, yes, thanks. Let me take another look at what I am doing. I'll let you know if I have any questions.

found the problem. thank you so much for your patience.
