I just think it's more of an exaggeration. Each person needs to go and do a field check. I mean if you died a bunch beforehand and didn't think anything of it till this particular time you died and you went to repair and it was 30k. Yeah duh you died before.
There is definitely a bug though, the other night while running with a PUG on the gree event we wiped (don't get me started) and I had 0 repair costs... then the next time I had 30k in repair costs... so something is definitely not right in repair land... and I repair after every death (repair droid FTW).
