Primed Sure Footed not preventing knockdowns at max rank

[Telogor]

As you can see in the video, even at a displayed 100% knockdown resistance, OriginalWickedFun still gets knocked down.  I think the mod was set to (100/11)% chance to resist knockdown per level, but then the decimal was truncated to be 9.09% per level.  This caps out at 99.99%, which gets displayed on the mod as 100%, but can still allow a knockdown .01% of the time.  I think all you need to do is set the mod to 9.1% per level, and it'll work perfectly.
