Strong boxes disabling skills

i have been playing with strongboxes.

i alc and then vaal researchers box and it disabled my skills completely. at first i thought it was lag but i used f1 and it seemed fine. then i thought it was a nasty mod from the corruption. 20 seconds passed and still locked out of skills so log to character select and it fixed it.

i thought it was a one off bug but i did it again in the next map. it seems to be when i corrupt the box, but it also could be a coincidence. it does seems like a bug due to it being fixed by logging.

thoughts?
