Found a bug i think, got 2000+ skill points for one day, but it's not clear why. It was 7 day, before that day there were 180 free points, during the seventh day I made 3 quests (Marksman class all lvls, Meat stew shef, Raphael's treasure) and killed a horde of zombies. After that I found out that I had 2600+ skill points
And the bike on the asphalt rides by about 15% slower than on other surfaces.
p.s. I like this mod, but I want a little more difficult
