This is an update. The dev simple has some version number issues.
The content he want to put into v10 part 4 isn't there yet, thus the "unambiguously" nummering of those. Instead of having v11, v12, ... we are since long in v10 part 1, v10 part 2, v10 part 3 and since not so long in v10 part 4 subpart 1, v10 part 4 subpart 2, v10 part 4 subpart 3...
What can I say version numbers, if I would make a game, I most likely open my big dictonary on a random site and use the random word where my finger ends as "version" number. If I'm in a good mode, I would try to avoid having the same word twice as a "version" number...
Anyway, the development of LRH is neither in a remake limbo nor in any kind of other limbo, just some strange decision from the dev on how he name the newly released parts - also be happy that he didn't go through with "I release v10 when it is finished".
