Anyone else having anomalies with the testing version and the firefighter career?

It was working fine before, without any mods except nointro and no building sparkles, but when I added AM a few hours ago (yes, the testing version that is so darn hard to find if you search traditionally), oddness popped up, but only in the firehouse.

Oddness being:
Wrong cursors (walk on sink, grayed out on treadmill) but clicking produced the correct options.
Ambient sounds from 'building disaster' (the grocery store muzak in particular) would persist inappropriately.
Hang on promising new want. (3 minute hang, complete image freeze, alt-tab to other window worked but nothing in Sims did.)

All eps, up to and including Showtime, installed. Only mods mentioned in use.
