Clamber not working properly

I don’t know where to report bugs, as Halo Support won’t give me the option.

About 1 out of 6 times I will try to clamber a ledge, holding the stick forward, and my character will do the clamber animation then drop down, failing to actually get on the ledge. I’ve been killed/lost time several times because of this bug. It definitely needs a fix.
