Ok, so there was an update two days ago..
Land transfers are seriously messed up. I sold a property, received the money for it, both myself and the buyer had a record of the transaction on our accounts, yet the land never changed hands. We had to do it a second time a day later for the transfer to stick after a Linden looked into it a confirmed that a) money changed hands and b) the transfer never took place.
I bought several properties last night, and while it showed my name as the owner, I could not build on it or return the previous owners items for in some cases 2 or more hours later because for some reason I wasn't 'fully' the owner of said properties.
Sim prim counts are borked.. Sim usage of -110 out of 249 prims, wth?, says my parcel has zero prims available, and zero prims used. Most of the sims I visited that I bought land in had a negative number.
Several mainland sims that even only had 2 or 3 main agents were being blocked from TP (please try again.. took 5 retries to get into the sim). The sim wasn't down, because I could IM people in the sim I was trying to TP into.
This is pathetic.. roll back the "update" until a release that works can be issued.
