This is not true, IR3's code has no references to AFH. If AFH worked with IR3 in 1.1, it must have been from AFH's side or due to a third-party mod.

However, the Patchset has support for AFH. From the Compatibility page:

Advanced Fluid Handling is unlocked with Steel analysis packs. Only Tier 3 pipes can be made.

EDIT:

Oh, you just want to have the Tier 1 and 2 technologies back?

Commenting out require("port.mods.advanced-fluid-handling") at the end of port/updates/mods.lua is enough to restore the default behaviour of AFH, which should still be playable.

If you're wondering why I made these particular changes to AFH, it's solely for balancing reasons. Fluids are used all throughout IR3, and I feel that this powerful type of pipe should be unlocked a bit later in the progression.

Also, I didn't like that the recipes require components from the previous tier. IR3 doesn't tend to do recipes that way, so I condensed all the tiers into one.

Thanks for answer! You right, i did changes in already patched zip, but should do it in patcher haha. Thank you for patchset, awesome work!

For anyone else who wants to make changes like this, changing "port" in either location should work the same - the one outside the mod gets directly copied into the mod.

You should NEVER edit the contents of "patch" or "input" directly, or the patch program will get quite angry.
