To finish my build I need burr weeds, I've plugged the haze ages ago and all of a sudden after meeting Wendell there are no burr weeds at all I check the resource scanner it says they are scattered everywhere mainly near the wood pile but when I go to where they are marked there's nothing now I can't finish my build the way I want it is there anyway to fix this or what is going on?

Seems to be a current issue, I'm having the same problem.

A little advice - try making the actual issue a part of the title in your post. The entire point of this forum is to ask for help; doing so in your title is redundant and actually makes it more likely someone will just scroll by.
