Uh, that's not happening for me, so it's not the client. Has to be something on your end. You using any mods?
Not sure it crashes you just can’t swap for a certain amount of tlme even if you log out and log back in. It’s a pain but think it has always been that way to discourage swapping players in and out when you are in a fight.
There has always been a combat cool down timer in UO. How many times have you gone to your house and get hit by anything and can't log on another char because the auto defend kicked in and flagged you as being in combat?
this is the easiest fix ever add the line was this player in heat of battle if no log in as normal...
It is an intermittent issue on my Win 10 laptop. It has never happened on my Win7 desktop. No heat of battle required. It has happened when switching between my blacksmith and my imbuer characters. Both of whom never left the house.
I have not had this problem, and yesterday I was changing characters in rapid succession, seeking an item I knew was in a bank box, but not which character had it.
What exactly do you mean by "CRASHES" Waiting for the cool down timer is NOT crashing. Heat of Battle prevents your char from completely logging out basically the same way when you do not log out in a safe spot. This is not a "CRASH" but is by design and to my knowledge has always been a part of the game and yes the CC does the exact same thing.
After the character is logged in the client becomes non-responsive to mouse and keyboard. After a some time Windows say the app is non-responsive and asks if you want to wait or close it. If you choose close Windows asks if you want to send diagnostic information back to Microsoft. If you choose to wait it stays in this condition until you give up waiting.
If I have waited 5 minutes between character changes and it still happens. So not a cool down issue.
Last resort wipe EC and do a complete reload because it sounds like something is corrupt.
