For some interesting reason I can't remove certain containers, note that those containers never pulled correctly, however, I should still be able to remove them.
Alternatively, how to send info to send mikrotik a supout file and create an official bug around this?
Hardware: CCR2004-16G-2S+
Software: 7.19.6
Note that those containers are "hosted" on a tmpfs drive.

Note that removing/deleting tmpfs doesn't solve the problem either 
Thank you for looking!
