The red dot shows up in *some of the single exposures from 2017 and not others

Huh interesting. Might be a supernova but the exposures it is in vary from 2015-2018 and so the exposures it isn’t in so would be a bit odd

Are those all in the same band? It looks like it’s easily visible in all the z-band, most but not all the i-band, and none of the r-band? Each individual exposure was taken in different conditions, so they’re not all equally sensitive – in particular, the seeing can vary quite a lot, and blurry seeing can make it much harder to distinguish a point source on top of a background in situations like this!

Yeah looks like its visible over all z band exposures, so not a transient for me. Probably a galactic star that’s just a little too faint for gaia.
