So I used to have a Worldedit version that could stack diagonally in 1.7.10 (forge), presumably between WE versions 4.3 and 5.6.3 according to worldedit changelogs, but on my new machine running 1.7.10 forge again, no version of WE I drop in so far has diagonal stacking. Yes I only leave one in at a time, and no I can't transfer from the old machine because it's fried. A few weeks ago I tried 5.5.8, 5.6, 5.6.3, 6.0 beta 01, 6.1, 6.1.1, and 6.1.7.2 before I gave up. After discovering the changelogs today I tried 5.6.3 again, but the game acted like it wasn't even in the mod folder. Theory one is that 5.6.3 is somehow too new to be recognized. If I remember right mods from old versions can sometimes work on new versions but not the other way around. I assume 5.6.3 should work because one of the changes was "- Added support for CraftBukkit 1.7.10." but I don't know anything about bukkit. That's everything. Before someone says to drop 1.7.10, I just like it because it can run all the mods I need to make functional star wars ships. Multiple flight mods, wireless mods, plus lasers and carpenter mods etc. Quote Edit
