BasePower not found: <0.2.6> <1.4.0>

I've been having this problem for a while now: sometimes, when I enter a door that leads to someplace else in the mission map, my character never comes out of the other side. For example, in Tin Mage's TF you enter the Vanguard conference room map, and have to click a door to go to the map proper. Some times, I don't come out of the other side; instead, my screen stays black. This happened again today during the Silver Mantis' TF, in the final mission: I entered the door in the cargo ship, but never came out of the other side.

This never happens if people port me to the new location, only when I go through the door. And a weird side effect is that my movement keys still control the camera: people see my character standing at the door as if he'd made it through, but they can't even use Recall Friend to unstuck him. The slash commands /stuck and /sync also do nothing. When I say I can still control the camera, I mean that I can move around and still see what's going on, but the camera is not attached to my character: I can even go outside the geometry.

It's a weird state that maybe I should record with Fraps next time it happens, because it's difficult to explain how badly the client breaks when that happens.

By chance, I was running the game with the console up today (my loading times have been awful and I wanted to check the reported times), and at the moment I entered the door, the console spit these:

BasePower not found: <0.2.6>
NOTE: this is likely due to a data mismatch between the client and the server.

BasePower not found: <1.4.0>
NOTE: this is likely due to a data mismatch between the client and the server.

I am pretty certain that all my data files are perfectly fine, however. I used the 'Verify All Files' option and it found nothing, and I also ran a MD5 sum and compared it to my laptop's COH installation, which updates separately; they match. So something else is causing this to happen, only sometimes, only when going through mission doors.

I know, this is a rather vague report, but it's all I got. I first noticed this problem when doing the Tin Mage TF when it was first released, so it might be something that broke in Issue 19. Incidentally, this is also when my zoning time got really slow.

That's really weird. A Data mismatch could be anything. You'll probably have to verify your components to see if it is anything on your end first. :P
