English version 1.44:
"Kill an assassin" => is correct in my log - I got 2x XP. 40176 for killing Groblar and 25296 for turning Groblar's offer down to kill Sigurd ("kill your employer". Did you report to Sigurd afterwards? Gave 2400 gp and 1500 ranking XP. -1 rep is the same.
English version 1.42: (have to solve a few others until I can verify this for 1.44)
"merchant wants amulet", gives 47616 XP. I gave the correct answer to the ghost, got his warning and passed this on to the merchant. There is a minor glich though => the merchant "gives" you this quest again.
"Entering the catacombs" => should be green in your log (in earlier version 47616 XP, now 0 => have to verify this)
"Trapped inside catacombs" shoudl be green in your log => please, check both. In both cases, you're in the catacombs, so the quest is finished.(always 0 XP)
So far I have watched this in a few cases => you get XP, but they don't flutter up and you have to check your XP stats with a calculator. So far only in Act 3.
