If you installed the fixed files manually, it should work with the Injector. However, note that the issue will persist if you then load an old savegame from that level. You’d have to start the map from scratch in order to have the fixed settings on that particular floor. Type “changelevel eoe7” to reload it with your current gear.
Hello Negke, yes that was the issue, I was loading a previous save (so the patch was…negated)
I tried your method and it worked, thought just to mention that it started me only with 50 shotgun shells (lost all my guns and ammo) plus was obviously playing on Normal (or even hard) judging by the number of enemies (72 for easy, 88 after your suggestion).
Overall your solution allowed me to continue playing the game, so many thanks.
