Hey! It's a kind of nuisance in terms there is not any permanent fix for it, but usually you can deal with that as follows:
1) try click the console/use PDA in hand again, it might load up again. If it gives an error message, tick the "don't let this page to give messages anymore" and move away/throw item out of hand, and then try again. It's usually good idea not to open PDA/a console right after reconnection or login, wait a minute or two to do that.
2) if this happens to happen a lot, clearing Internet explorer's browsing history and BYOND's local cache will usually make it less frequent for a while. Do this every now and then when this problem starts to annoy you.
To clean IE browsing history:
a) access IE (start menu type iexplore, open)
b) wipe (CTRL+SHIFT+DEL hotkey to access the clear browser history thing)
To clean BYOND local cache:
a) access Byond hub/launcher
b) top right, gearbox icon -> preferences -> games -> press clear cache.
IE is due to the game uses it to do a variety of stuff. And BYOND happen to get a bit flipped from time to time. These two tricks will usually work to other problems that more or less break something for you. If these do not work, doublecheck that your BYOND is up to date (stable or beta), at the BYOND hub.
