launcher Playing mods would go back to launcher

[chubbers101]

 

So for some reason every time I try to play any sort of official mudpack hexxit/attack of the b team, when I start and click play it would load through the launcher screen and auto refresh the launcher screen to empty (with no logs) and any time I click play it keeps doing the same thing, I tried reinstalling launcher and .technic folder 2 times and stil having this issue. I'm not sure if this issue is just me having windows 10 but I never had this windows back when I had windows 8..

post the logs

Error logs can be found when clicking the Cog-Wheel button on the top right corner on the launcher window.
If you can't open the launcher the logs can also be found inside %appdata% -> Roaming -> .technic -> logs

Paste the content on pastebin.com or paste.ubuntu.com and give the link.

[18:27:10] [Client thread/ERROR] [FML]: The following problems were captured during this phase
  [Client thread/ERROR] [FML]: Caught exception from xreliquary
  java.lang.NoSuchMethodError: lib.enderwizards.sandstone.Sandstone.preInit()V

ah, this error again. This has happened to others and so far I haven't seen any other solution than to delete the Reliquary mod from the pack.

Looks like missing libSandstone to me. There's a 1.0 version for 1.7.10 floating somewhere. It *should* be downloaded automatically when the modpack starts to modpack_directory/mods/1.7.10. One can try to manually download it and place there.

Edit: after more testing it looks like the hosted LibSandstone jar was changed without any version change so Reliquary included with hexxit 3.0.0c doesn't work with that version any more.
