With two photogrammetry models inside (loads of polygons), the file takes some time to load on first play. There is also a small glitch that it wants to occasionally open up a description when you first click into the tab. hit the back button and it should run as normal. I believe this is due to there being no collision on the door, so clicking in that area opens up the first document it sees inside. Item descriptions also seem to unfortunately only work in full screen, as otherwise information is cut off.
Apologies for the inconvenience, and thank you for your patience!
