Hi Studio 397, i don't know if it's a bug but with the latest release from april, i noted that my tracks (didn't test others yet) are having the puddle effects on the curbs. When i made the tracks, i didn't check the puddles effects on curbs because the water is not creating puddles on top of a curb but well in the track near it. Now i have the puddles on every surface (track and curb) and it doesn't look right for me. Anyway, your update is a bomb, congrats to the great work guys, hope my feed back help you Cheers .
