Lo-Fi Games

Hi,
This probably is not restricted to the current version 0.91.9 (i just started to play again after i paused at version 0.6x) but recently i noticed that one of my characters has a strength cap at 45, i have no other character with any attribute near as that so maybe this has nothing to do with the value but with the fact that the character was imported from an older version.
Maybe this is working as designed, please tell me if this is the case, but i noticed that the progress bar does increase, but as soon as it reaches 100% it just resets but the strength value stays as 45 (no matter if i reopen the character sheet or having it closed during the level up).

I just noticed that the strenght of the character is now at 46!
There was no update though, thats why i can think of two possible explanations:
1. i removed the large traders backback the character was wearing all the time before, i bought it in the old world back then and just reimported it with the character.
2. Or this time the level up was caused by fighting, the problem described in the start post (progress bar does change but just resets after reaching 100% without changing the strenght value) was allways related to normal carrying heavy stuff. Maybe there is just a cap for strenght increases by carrying, maybe when 45 is reached only fighting can increase the stat any further?

It could be both because right after removing the backpack i had a number of fights with the character.
But the character is in fights very often so if the strength only increases by fighting it had to happen before (or i was just very unlucky). Ok it could be that during the fights the progress bar was increasing but never reached 100% and then after the fights ended maybe some normal movements/carrying filled up the progress bar but because it was carrying not fighting it just got reset (this is a clear bug then).

But i think it is realated to the large traders backpack. If only fighting can increase the stat any further, then carrying should not increase the progress bar!
