Wow, I honestly can't thank you enough for taking the time to research how to get my mod working. And no, it's not just a user error on your end
I was told a couple of days ago about the 31 maximum lines within the upgrade.2da file by Fairstrides.
I have also looked into Rece's mod and I did notice the filler lines and was completely confused by them haha. BUT, I noticed when I installed Rece's lightsaber mod not all of his lightsabers apply all the properties of the vanilla crystals or his own.
I have been messing around with ways on getting my mod compatible with the VANILLA crystals and with my personalised crystal mod, as I was going to overwrite the weakest vanilla crystals. However, I'm going to have a good read of your message and look into the column rows and follow the rows you've advised.
For your assistance, have a conveniently placed Meerkat:
