Happens on all pond water equipped maps.
22:47:17 Warn: Shape '???' contains water texture however it does not carry a property "class=pond". Consider creating one to speed up the detection!
This will go off about 10 times in a second.
was able to test this draining perf in a 10 player MP game.
I used zues to spawn in 10 amphibious vehs i place them on land and then in the water. when placed in water they drop FPS by a large amount. when on land they cause no FPS drop.
our workaround has been to fill in all the ponds with concrete blocks so no one can go in them.
