I’ve been getting some pretty strange riverbanks, and I think it’s probably a bug on the mapgen; whenever rivers/riverbanks are generated, they have these weird inverted-L strips of land on the middle of the river. I’d guess it’s some problem with the mapgen identifying these as _not_ connected with NE land tiles or something, but I couldn’t find anybody talking about it. Sometimes they appear in the middle of rivers or beside bridges too.  
I use the standard mapgen settings, Magiclysm and the “no rail stations” mods, but I don’t think any of these have anything to do with this bug. Below are some screenshots of the wonkiness.  
Thank you guys for your work! c:

Edit: I’ve been getting these from 10615 onwards, I think
