Interesting. Did seom testing. Hide then immediately go into TBM the character still has a BA.
If i used firebolt and entered TMB before the bolt hit i entered TMB without my action.
Thanks for testing! The results are indeed interesting. It feels like an extension of the system whereby characters entering combat after it starts don't get to act until the following round.
Larian have put some thought, then, in the way the action economy interacts with the real-time/turn based barrier. I guess all we can do at this point is wait and see how it all shakes out in v1.0.
