When I did the tutorial, I got ahead of it in several places which caused some issues, for example when it told me to go do one thing, I would start on another (multitasking) like collecting seeds while collecting wood for example, I gathered too much and later when it asked me to go collect seeds it wanted new seeds, not counting the ones I'd already done, this can cause issues with getting stuck and slowing down the game significantly. :)
So I have several versions of missions. One mission type is COLLECT X amount of things. Another mission type is HAVE X amount of things. So I have that functionally built in. I may have just not set the right mission type for that mission. Was it the seeds mission in particular?
