[PC-STEAM] [0.90] [COOP] cant see my team mate and see stuff

From the very start of our game session my team mate is on my screen half stuck underground and on rafts. everything my team mate takes or harvests i can still see it and when i go to harvest nothing comes out. like yucca tree is fully grown but my team mate already hacked it. and we cant sleep or save game.
before we started my team mate set the game to creative but only she is affected by this not me and i could not change it before we started. we just restarted and now all seems to be in order again except for me not being in creative mode like my team mate.

Thanks for letting us know about this panda1099,
To clarify: you are playing the game in survival mode but the host is in creative is that correct?
