Retailing with "Svalinn"-Shield seems to be bugged at sublimed ground - does nothing

Header says all.

Here some emotional information:
Since i have chosen "Svalinn" for getting some ranged Retails, for such a reason as mentioned and more, it is not understandable why "Totems" or other "Spells" should be a better Option for somebody who choose to play Blockbuilds.

Greetings.
