quest not working

hello i had a quest to survive 800 in survival but it didnt work even though i got into 6000.

There was a bug in version 1.1 that this (and other quests) did not complete. Can you check if you are using the latest version (1.2)? Also, this still happened if you started a game with 1.1 and then upgraded to 1.2. Would be glad to hear back from you! Thanks for reporting!

Ive been using 1.2, but i had 3 different quests i canceled one to get the survive quest, then i started a game immediatly which by then it didnt work when i got into the point where the quests shouldvd been completed. Also I want to note that i pause the game and multitab alot and maybe this is the reason.
