Last week I had a B739 showing at 106% technical condition. I figured it was a one-off bug... then I found 2 more showing the same thing. An hour (2 game days) later after all 3 aircraft had their next A check they were all back to normal (98-99%). My point? Excrement happens and IMHO not every bug is worth taking the time to report... If it doesn't affect the financial or operational state of my airline or anyone else's and its not an ongoing issue I'll just leave it alone.
That particular bug has been reported and squashed about a half dozen times already. The thing is, a bug is defined by when software is not operating according to its design. By common sense design, something cannot have a condition greater than 100%, therefore, if it is reported as 106%, the software is not operating as designed/intended. Sure, in the grand scheme of things, it's not material to the overall operation of your airline (or anyone else's), however, if there are sloppy things like that throughout the entire game, you would have far less confidence in the software functions that matter the most to the playability of the game.
