If you become immobilized or hit by binding roots on slanted or non-flat terrain, it can potentially bug your character out and consider it “falling”
this means you cannot cast anything, change anything, move, remove the condition, nothing.
Even shouts and instant cast abilities will not function due to “falling” caused by immob / binding roots
