I understand your reaction.
Okay, I think this is all related to the same error (not sure as it doesnt give a single error obviously):
I just added a saveposition and savemoney etc. script. When I log in now, first I’m at the right place and with the right amount of money. Then however, suddenly my character falls down for 30 sec XD and returns to -1$. So my conclusion would be that this is because somehow my system has the 'savemoney’script, but somewhere it also has a ‘reset’ line.
The banking might have something to do with it too.
