The changes noted above appear to kick in the week of 7/20.
New-to-Buzzr eps on 7/13:
Concentration 70s picks back up with 1031.
LMAD 80s Picks back up with 266...then gets messy. Run jumps 3 episodes (skipping 269-271) on Thursday, before jumping ahead 33 shows the following Monday - from 273 on 7/17 to 306 on 7/20. Since someone's inevitably going to ask why. Obviously no idea. There's a hundred different reasons (for the hell of it, weird episode numbering, tape damage, coming back to it later, something getting shuffled around in screening at Fremantle/Buzzr due to all the Covid-related workflow changes, who knows; any guess would be speculative).
On 7/20, more new stuff:
Match Game-Hollywood Squares Hour resumes with episode #76.
New Blockbusters also shows up on 7/20, picking back up with right where they left off in November '81
and then on weekends:
Now You See It, which I believe *has* been running new-to-Buzzr shows in it's upgraded timeslot (Edit: Nope), reverts back to #23 as it drops back into overnights.
The new run of Monty's BTC is new-to-Buzzr, picking up a couple weeks into the All Star era with show #45.
Body Language starts fresh episodes and continues where it left off as well beginning late-7/26.
(And on a personal note, I'm always sad that Rafferty's CS can never seem to stick around or get more than the first 20 shows aired - it's actually my favorite run of the show)
