EDIT: UPDATE: THIS IS NOT AN ATTACK ON THE DEVELOPERS OR AN ATTEMPT TO
UNDERMINE THEIR HARD WORK. THEY DO NOT HAVE A CORPORATE TEAM OF BUG
TESTERS ON THEIR PAYROLL, SO THEY NEED TESTERS TO LET THEM KNOW IF THERE
ARE PROBLEMS. THUS FAR, THEY HAVE RESOLVED ALL ISSUES PREVIOUS TO THIS
BUILD. WHAT THEY ARE DOING IS EXTREMELY DIFFICULT.
It looks like the Full v 5.0 was not quite ready for prime time. New Level 5-2 had graphical corruption & there were disappearing weapons in level 5-1. Probably other problems as well.
