I've skimmed through half of the comment section but saw people both saying that LAO 2.0 + LAO III will not work and also that they will work together, so I figured I'd ask properly: if I plan on using LAO III, would it also be beneficial to install LAO 2.0 (or a collection containing it like Mamba's Mod Merge)?

Or is a LAO III a straight-up upgrade, making the use of 2.0 entirely unnecessary?

Sorry if I missed some obvious (or implied) information anywhere but since other people are asking the same and people are responding both "yes" and "no", I believe I'm not the only one confused by this... also big thanks to the author for all the legendary-tier modding work for TL2!
