All the great mods ends up the same way, once they become awesome, the author/modder quit and we never hear about them again for some very popular mods, some people start to work on something similar and do a pretty good job (Project Red in replacement of Red Power2) and some mods are never found again despite them being awesome (The Zeppelin mod in 1.2.5 and the Ships and Boats Mod also for 1.2.5)
