Every time I chop down a dandelion it breaks down into 6 weed stems and yet I can only carry 5. This gets very annoying when my base and the weed stems are far away from each other; I end up having to go back to get just one weed stem when I should be able to take them all in one trip.
I'm also experiencing a similar situation that you are having but on the Xbox. Once I built spikes around my base there was a big swarm of larva that spawned and tried to destroy my base, sometimes there is a big swarm of soldier ants instead. It's very frustrating.
