1.19.2forge 43.2.6
when modernfix installed with connectedness in the same time,connect texture support by connectedness can't work,such as it still have gaps between glass block

Can't reproduce with only ModernFix and Connectedness installed. I added the Stay True resource pack and the connected textures from it seem to work as expected.

As far as I know this is not an issue in the latest ModernFix releases, at least with the default config.
