86 days in. Me and a friend we're exploring a ant layer. I found some rotten bee armor and a chip. I have previously already blew open the door at the oak tree. For some reason the door I fixed and locked again?... Anyway to fix this without starting over? Anyone have this problem?

(I know. It's in early access.)

I found a salutation on the forum. 

 

Known Issue: Oak Tree Lab doors will not open for players. 
Workaround: You can attempt to enter the Oak Tree Lab using the back entrance through the abandoned anthill in the south-east area of the oak tree. However, players may need to start a new game in order to continue progression while we continue to investigate.
