After the programmer of GZDoomBuilder MaxEd has vanished for uncertain reasons, people feared the worst as the latest release didn't cover various critical errors that made the mapping tool usesless to some of us. Good news is that ZZYZX took the duty on his own and started a new bugfix fork on which he takes care all the problems and seems to continue the development of GZDB. Whether or not MaxEd returns after a while, the community survives it all, thanks to the people who offer their help. Thanks kindly for your dedication ZZYZX, currently working with the new tool on my own - and it works!
