some of these, you might be able to work around, some are sort of fixed or should be better in 4.6, I would think.
what version of engine are you using?
well as all these problems can get pretty in-depth, and although I don’t have the solutions for all that you are having problems with.
I would take screen shots or videos & possibly any BPs or code you are having problems with and post them to answer hub, individually of course.
post links to any or all solutions back here, I would like to see them myself.
