The floors are eating us

I and others in the Sikkima sim have been having problems with the floor 'eating' us. Basically, the floor looks like its gone phantom, the people bounce a bit, then stabilize and go back to normal. On a locked non-phantom floor. Its very annoying and happening in two parts of the sim and been going on for two days now. Can someone please help?

Thank you.

Unless the floor in question is on a sim border, this is something that needs to be bug reported. If they -are- on sim borders, then what needs to be done is a pair of slim, invisible prims need to be laid over the floors in question, and the center of each of them has to be on on each sim, with some overlap.
