System Information windows 7 geforce 550ti
Operating system and graphics card

Blender Version
Broken: Hash: 7260a69
Worked: (optional) Hash: Blender 2.78.5 195d0fb 10/may/2017 from builder.blender.org

Short description of error
New changes in Bevel modifier messed up particles hair distributions made in old blend file (blender 2.77)

Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps

tracking_bug_4.blend
With the blend file above uncheck bevel modifier's visibility eye and see the particle will show up and check it again they stay on place.

Background about the file (not the one above ) it was made in blender 2.77 and has particle hair system in it, and has a group in it. I tried replicate it and tracked the bug down to this version.

On Friday in irc Sergey was so eager to get file but i was so busy and i was thinking that the bug will go to mont29 :P finally i see that it is for Howardt, sorry ;) since Mr Howardt is so busy with his student, i think Ideasman42 should get it :P I should let you people to decide about that :)

Thanks for the report, but no bug here, it’s just psys that needs to be 'kicked' again to be recreated, touching to some modifier visibility (or adding a new one) is a way to do so, but you can also e.g. add a particle/hair to the count, etc.

Ideally that update could be forced automatically at read time but… particles are barely maintained alive currently, and only critical bugs are considered for investigation and fix, not that kind of glitch (which is common all over psys anyway).
