Request to add back the original tank recipe. I am running into a problem with other mods still requiring the original tank in their recipes.
Thank you

You can do it in the mod settings before the game start.

Sorry for the late reply.

Some mods may need the vanilla tank as ingredient for other recipes. You will need to unhide the vanilla tank recipe by enabling "Keep vanilla Tank recipe" option. Please see the FAQ section for details.

FAQ

Q: My other mods need the vanilla tank as ingredient, how can I unhide the recipe?
A: If you are first time using this mod on a game, enable "Keep vanilla Tank recipe" option is enough, which is under "Options" → "Mod settings" → "Startup" tab. For an ongoing game, you may also need to check the "Force enable vanilla Tank recipe" option (under "Options" → "Mod settings" → "Map" tab) once, then save game. The later option needs to be unchecked again after activation, because this option enables the recipe REGARDLESS of whether you have the requisite technology.
You may also need to check these options and save game, if you want to disable/uninstall this mod.
