for an example: when i try to put a toggle latch on the ground or somewhere else my screen freezes immediately, happens with all like the timer , the sequencer and so on but game is still running, when i log back in to the game the toggle latch is on the wall and the game runs how it should, happens only when i hold it in hands, maybe it´s a bug in the projection before you put it somewhere

Does it crash when you do it? If so, can we get the crash?
Also, what mods are you using?
(Please, use pastebin/gist)

sorry no crash log, game still running just frreezing screen

and here is the mod list

everything on mc 1.7.10

The problem is likely to be shaders, can you reproduce without them?

turned of the shaders same problem
i´ll try it without shadersmodcore insalled

ok got it, shadersmodcore is the problem, after uninstall it works
maybe it is an old version

No longer an issue on newer versions.
