Hello, I'd some problems with amxd file. Two patch DensityM4L_Fx.amxd and DensityM4L_Instr.amxd including bpatcher abstractions with the same name. When the files (unfrozen) work inside own folders, all is OK but when freezing two devices, the first devices loaded replace all subpatch abstraction name in the second 3 4 etc... e.g. DensityM4L_Fx include an abstraction (bpatcher) about, while DensityM4L_Instr own about. if DensityM4L_Fx is loaded for the first and DensityM4L_Instr successively, this->about is replaced by the M4L_Fx. Same thing for all subpatcher causing a disaster! I done some tests and discovered this occur only if devices are frozen. Please send me a feedback, thanks regards ape
