Forge crashes immediatelly after loading a pre-1.8 generated map (generated around MC 1.6.4) with a StackOverflowError.
Forge version: 11.14.0.1247, no external mods installed
crash report: http://pastee.co/ukgbaQ
I played this map in Vanilla MC (no crash!) before I try to play it with Forge.
Previous Version running the map: 1.7.10-Forge10.13.2.1230 with some mods installed.
PS: 1.7.10-Forge10.13.2.1230 to 1.8-Forge11.14.0.1247-1.8 works with some missing items:
