This mod get's really confusing! The mod author (authors??) should really do something about consistency, naming and version numbers. The last incarnation of this mod was named "TrueLight 1.2 SE v1.3 Special Edit" and was made by several authors. It already got two version numbers in the name and was aparently made by a number of authors.
It got erased and now it seems there's only one author and the mods name has changed, too.
The mod structure doesn't help either. There are three "lighting" options and how should I know what's better? "Best lighting", or "lighting 1.3"? Even more confusing: While the version number has been updated to 1.6 the readme and folder names still say "1.3".
Very very confusing. You need to do something about it. If it's a matter of time then take more, slow down. No one expects a perfect mod overnight. I guess you see what hasty work does, just look at the latest bugs of this mod. Please, sort it out, bring some order into the mod and take your time. Thank you!
