Reflexive Teleport will stay on the screen while you choose where to move after triggering successfully. This blocks some areas to move.
I think I've seen some other similarly-triggered cards do this. As far as I can tell, it is distinct from the "oops, this card has failed to complete its animation and will stay in your face for several rounds" problem: as soon as you choose where to move, the obscuring card goes away. As a temporary measure while waiting for any bug fix, you can drag the map around to see the obscured areas.
Resurrecting an old thread just to note that this bug is still out there (just in case devs thought it had been fixed in an intervening build). Gray
The ever industious Sir Knight has previously listed Dodge and Hard to Pin Down as having the same issue.
I would like to report that this is still an issue. In my experience it happened while i was encumbered. Dunno if what is described in this thread is fixed or not. But apparently if you are encumbered on top of dodging (as a dwarf) dodge card stays on screen till you select facing. So it's either a unique situation or bug hasn't been fixed yet. Just thought i would report it. Sorry for necro!
