Custom Trailer Crash issue

Hello! I recently started using Zmodeler to try and do simple things like turn in game prop trailers, into working trailers. I succeeded with one trailer because I pulled the wheels off of the “trailersmall” in game trailer. I went to try and make the wheels that were already on the prop into working ones, and now it is crashing. I disconnected them from the prop and set them up the same. Not sure if the crash dump is useful here but it’s here just incase anyways. Thanks!
