Nope not some insects or foliage infection.............
I have encountered an issue/bug in the Redhorn Lodes. When I have used Hedge in there I get stuck in combat and unless you can retreat somewhere you will end up dead. Relogging clears the fault but its obviously a pain in the ass.
I raised a ticket today and a GM contacted me in game, apparently this is a known issue and can happen with totems too. A GM can clear this in game but it would obviously take time.
Hopefully this will be fixed at some point ~ you could try it but if it happens once it will keep happening. Will post whenever I get any more info.
