Update: I've been trying to replicate this bug with the 1.4.3 version, but I didn't get kicked out when I get a failure at day 125 so I'm very confused now @@ but yes, maybe the primary task is having a failure or something funny happened in the code during the process...?
I'm not sure, but the amount of points shouldn't be the reason because in order to make things work with the small events, I have to reset the "hunt"/daily task value everytime it exceed 2 or 3 points (that's why the MC is asking you what to do every 2-3 days) and the maximum amount of points you can obtain is 300 per task, so... I'm drawing a blank here :'D
I can only hope this bug will not cause a huge problem in the future >_<;
