Blender Version
Broken: (2.78 release candidate, 0e5089c)
Global Undo automatic turning off after using "loop tools"
Exact steps for others to reproduce the error
2 cubes (or other objects) > edit mode > select 2 polygons > select "bridge" from "loop rools" > global undo turn off
Same problem with other options from "loop tools"
https://builder.blender.org/download/ has downloads for nightly builds.
i tested looptools & each tool it contains & found that there was no error related to Global Undo turning off.
i have come across the global undo bug before in bsurfaces, so I'm familiar with it, it's just not appearing for me in this case.
download version from buildbot:
