Hey Marcus, thanks for the quick response mate!
I followed your advice, and disabled override with formats in Events List/Archives but that didn’t affect the front page.
When I disabled formatting for Event Pages, this then caused the event posts on the front page to behave like regular ones (with the “more” tags working, which is all I really want), but of course without the map and other goodies from the formatting.
Unfortunately, I couldn’t the code you gave code working, but from what I understand of it, it will disable formatting on posts only when they are on the home page, which will remove the maps and stuff once again, but I can live it that if it works.
