People on app only are reporting being unable to train on the 3 buildings. Sometimes for me collecting on the app, except barracks, of course, bugged thoroughly, doesn't free one slot but works fine on browser.
As it's a pretty complicated issue, our development team is still working on resolving the barracks bugs. As long as the status of the bug reports is still on "confirmed", the fix is not (fully) implemented yet. When it gets changed to "fixed", it should be resolved. By then we will of course also post an update in our release notes.
Thank you for your patience and sorry for the inconvenience caused.
apparently is fixed but I will only know for sure after I collect the golems. ANyway the troops being trained disappeared and the supplies used were not returned
only the barracks is fixed the mercenary camp still has restricted the number of slots you can train - I used to be able to train 5 now can only train 3 - really not great since my I just processed two squad upgrades in the last 2 weeks!
Before the change, you had 5 slots total for all three buildings. Now you will have 5 slots for each building, once you upgrade it far enough. This may also require researching all 5 troops to get all 5 slots.
Again, before that change (not this issue, but game change, read patch notes) there was only one training queue, which has 5 slots opened by upgrading barracks. Now there are 3 different queues, and each one get more slots by upgrading appropriate building. Merc camp gets 4 slot at level 5, and 5 slot at level 9.
