Bugs in published island

Hello, I have a small problem. I have my project in UEFN and everything is fine. When I start the game session from UEFN and test the map, it works perfectly. However, when I publish it and play the published version, it has some errors that do not occur in the UEFN session. For example, in my map there are several trees with physics, and in the UEFN session, they work well throughout the game. However, in the published map, the trees completely disappear when round 2 starts, and they do not reappear throughout the game. Also, since the last game update, I encountered another error. On my island, I have a device that grants regenerating shield under certain conditions. Again, in the UEFN session, it works well but in the published version, it stopped working. Is there anything I can do about it?
