Fishing spots showed up, although rarely in our old zones with a 3x3 pond size. However, I'm hoping we see them a bit more frequent with the newer 5x5 size.
I do see what you mean with the lava bridges, they should be either galaxite bridges OR metal grates. Personally I like the grates over the lava, but it just didn't look right having the + shape glowing. Also like that there was then no-where for Galaxite bridges to belong, so I compromised and that area got both.
I could see what it feels like moving the scarlet bridges over the (stone)mold .. and place the galaxite over the acid? Especially as the stone bridges don't look that different from the stone floors I've used ?
The acid is using desert sand as a border because something freaks me out over the bug-floor texture (not sure what, its just creepy)
