Ok, got the first quirk from 6.3 as well. In 6.1, I have a plane, preset material "Maple wood", texture woodbase4 scaled in Object space at  X 138%  Y 138 % Z 138%. I save it to a file and load it up in 6.3 and it became mapped in World space at X, Y, Z = 100. How come? I'm reporting this via Mantis... let's hope that glitches won't be popping up like mushrooms in the next days...
