5.5.1.1 only using 3 barracks

Hi there, I just noticed that the bot is only using 3 of 4 barracks to train troops. I'm using barch to attack (version 5.5.1.1), there is no error message in the log. The bot opens the training menu and then just closes it.

Anyone who can reproduce the issue?

i reproduced this using B.Arch, simple fix is to use barracks instead and just change barrack 1,2 to arch and 3,4 to Barb

Please using "Barrack" method, and choose your army train setting.
Im using only 2 boosted barrack right now :D
