I am getting compiling errors with some of the blueprints. First person character and the tutorial. I am not even using the tutorial. I think it may be related to the recent 4.12.3 update. It was working fine earlier though. I do not touch the blueprints. Not sure what is happening. But I can not do any interactive game play with my project.
I recompiled everything. Everything recompiled except the first person character. It has a bunch of warnings.
