Tiles not saving

[bigcity]

OK so about 2 weeks ago my tiles i was placing randomly stop saving. When using update level they just destroy them self's. I've tryed everything i know to fix this problem. The server options are fine from what i see.

savelevels=true
savelevelsmessage=true

I don't even get a rc message saying the tiles were placed. What could be the problem?


and btw i waited several minutes before updating the level.
