📋 About This Mod

NO LONGER MAINTAINED. THIS IS NOT INTENDED FOR USAGE WITH DLC8 ONWARDS.

In theory it should still work, but it is use at your own risk. Features in this mod are now covered by other mods, or the unmodded game itself.

With the updates to Yet Another Mechlab in v0. 93. 1 (and ongoing), there are a number of assets that will cause issues to YAML that are in YAMM.

Using the source provided on the YAMM page (version 1. 3m unfortunately, so not the most recent content) I have forked this into a maintenance version.

Anything that was added post 1. 3m will be missing - the hidden, unfinished superheavies (accessible via other mods) are not in this, as well as some Large Engines (though base YAML adds the majority of these). A number of quickfixes also removed, as they're now fixed by the base YAML mod. Changes noted in the 1. 3x Change Notes also applied.

Now I haven't just purged content that's been an issue - the COR-7A that is in this mod, is also in base YAML, but due to different asset naming, won't conflict so it's remaining in here (you won't lose anything thing), however the AMS fixes are included into YAML. The Arrow Urbie is also canonically accurate (intro date pushed ahead to 3073, added the missing arm actuators (you will lose 2 available slots as a result, sorry!), the missing XL engine, XL gyro, small cockpit, jumpjets, an extra ton of ammo, and the laser in the correct location.

Loadout order is also now default 4 (to compare with YAMLs default 5). Please ensure that YAMM (whether this fork, or the original version) is being overridden by YAML to not cause issues.

This mod is unlikely to receive any updates - unless I need to change something for compatibility with YAML. I may come back to fixing further things to get them working again, but don't hold your breath. That said, any canon mechs that have issues and got disabled in this fork are not lost to the ages of time - worst case they will resurface, in other Yet Another mods. SoonTM, obviously.

Use this INSTEAD of the old YAMM.
