this mod (https://mods.factorio.com/mod/extendedangels) adds one or two more tiers of several angels buildings but your mod removes the tech unlocking hydroplant 4 and salinization plant 3. I checked, without your mod the tech is there, but yours removes it
not fixed, the tecch is wáter treatment 5, its only afected by extended angels (the mod that gives the tech), ReStack, and yours, and removing yours the tech is available again
