I find it hard to believe they removed Fog completely as I still see it on official vanilla servers though. So I think the issue is elsewhere, thats why I was wondering if anyone else (like yourself even) has the same thing upon using the plugin in November update- and if you didnt, then I could just copy their settings and then i'd be back to normal no problem. Also they arent similiar they are IDENTICAL, both are exactly the same so it looks like a glitch even more so.
Also on a sidenote I had another question; when you click the green arrow to load a preset, does it need to play the full SET duration before a new one can load?
