Ok, it happened before I bequeathed my hotel and now it happned again.
The thing is: when You reach max available points in laboratory you can't earn more and then one day you get the quest with part of it to earn research points. Isn't that stupid? I can't do that so why do I get that quest? The game "engine" should check whether you reached your maximum andif the answer is "yes" then shouldn't give you such missions.
Admins, developers, hear me!

You can still create lab points to satisfy the quest. However, they become and give you 1 instead of an actual lab point.

You bequeathed, so you are playing some time.. maybe you already know why i had to lought out loud reading this

I play MT games for almost 3 years - started with DinoRPG. So yes, i do understand it quite good .

npfan, thanks for help. I knew it gives you reputation point but had no idea it still counts as lab points for quests .
