the only "fix" (not REALLY a fix if you're planning to release the item) for this is turning off dynamic shadows. anyone who downloads it would also have to have that turned off if you're releasing it, though. this tends to happen to a lot of deco sims that people make as well due to the high polys. id say if you plan to release it, keep to under 10k polys an for personal use make it whatever you want an turn off dynamic shadows. keep in mind with every update you have to redo the process of turning off dynamic shadows as they are auto turned back on when updating your game.
