Sometimes when I try to use one of these skills I seem to lag (all mice freeze, I can't build anything and round never ends) but a simple change of rooms proves opposite, although it's extremely annoying and causes lose of some saves. Another problem with these skills - you can not do anything with objects which were B anchored by another object. Example: put a box, put B anchored small plank on top of it. Now you can remove/make transparent the plank with these skills but can do nothing to the box. As a true mechanician I would really like these issues to be fixed. Thank you.
