It is a nightmare to tweak, as are most levels which have plates or bars linked together with anchors. If we all try to build levels with everything seperated it will reduce this frustrating tweaking problem. All you need to do in a line of plates or bars is to put in two anchors next to each other at every junction so the plates or bars are not physically joined to each other. You only have to do this in areas where anything is likely to be constructed. This problem should be removed from Beta 2 but until then this small change of design should help.
