@mrnyarlathotep: Thanks for the feedback!
I think I did a really bad job at making things intuitive ... basically how it works is:
the left assignment is the one where the bees feed, so you can get more of them, but if you don't have enough food/honey, then they will starve.
The ones on the right are guarding and also consume some food and will starve if there isn't enough. The ones in the middle are gathering and instead of consuming they will give you more food and materials to upgrade.
The wasps are more of an event that shows up where you can see the next weather changes, once their countdown is complete, you either have enough guards not to lose anything, or you lose some bees and honey.
Those flickering sprites are probably some bug due to me spawning the bees first and then moving them to their assignment and the engine doing some kind or interpolation of the position maybe ...
