Like every 6 months something impossible happens on my visual studio. For example the program enters an if it shouldnt. It evaulates to false but still enters. This happens because somehow it uses old cached intermediate files that are no longer valid. No matter what i do it refuses to build it correctly. Even clean and rebuild does not work, it forces me the delete project files and recreate them It probably an err on our side, especially aince clean dowsnt work. But it is quite annoying when it happens and gets hard to figure out what is going on
