I'll use the Brewery machine quest as an example.
The quest clearly comes after the player has access to MV machines.
The quest's description suggests making multiple LV Breweries or a higher tier one.
With that being said, the quest specifically requires an LV Brewery.

I think it is reasonable to make the quest accept either an LV or an MV Brewery, or just accept all Brewery tiers.

Not sure if there are other cases where this issue happens, but if it does, you can apply the same logic for those quests, the guideline being requiring a machine of a specific tier or above. For example, a quest that requires an MV machine should accept MV or higher tiers of that machine.

Does this comment pertain to 1.2.1? We made several of the earlier quests accept multiple tiers of machines to satisfy the requirements some time ago in the dev snapshot.

Closing for now because I believe this issue is already solved in dev as part of PR #272.

yea, I'm playing on 1.2.1. Didn't know there was a dev snapshot, but I did look my issue up and didn't find anything on it.

It was part of the massive quest book revamp we did. You can see details in the commit history, and as part of the pull request branch #272.

The dev snapshot is a client/server zip pair that are found under Releases. These contain all the progress so far towards 1.2.2, automatically generated from the latest commit in the dev branch.
