In the AMA it was said there'd be a beta patch released soon to specifically deal with the reinforcement bug. However, do they really think that's the only pressing issue?
I want at the very least for this beta-patch to restore those goddamn Skaven/DE loyalty events, too. You released content for a faction TWICE without bothering to actually have all their campaign features functioning, this was a quite literal slap in the face you need to make up for, CA! And the best way would be to actually fix it before you release more paid content.
That's the minimum of effort I want to see.
