Player gets stuck inside a high-sloped "speedpad" floor

Well, I was making my race map, my intention is to put a sloped speed pad floor, when I was testing it, the player gets stuck inside it. I don't know if I'm doing something bad, it should be logical if the player thrusts towards at the angle of the slope (of course, if the slope isn't super high).

The problem here is probably to do with the fact the speed pad teleports you into the sector's center by default. I suspect it probably doesn't account for slopes at all yet, which would be a bug with SRB2 rather than you doing anything wrong in your map. In the meantime, you could turn on Solid Midtexture on the linedef type 4 for your speed pad to disable the teleporting (Zone Builder probably calls it "Doesn't teleport player" or something). That way you won't get stuck in the slope.
