Well, to give a little "sneek-peek" of what I have planned for the engines...
1. No useless recycled-code from the old versions of the mod.
2. New networking?
3. New Dynamo Engine mechanics. Heating, cooling, etc...
4. *Maybe* New hand-book for reading about engines *Maybe*
More things to come?
EDIT:
Also more lag because why not.
EDIT EDIT:
I found what was causing some major performance issues... it was my 'waiting' timer I implemented awhile back that I made for future purposes. (I'm not telling. )
(Does anyone still read this stuff?)
