Short description of error
Well what can i say. in 2.78c alembic sequence of files loaded without a problem. and in 2.79RC2 they load however only first frame. they don't update what is intresting that... They are 2 sequence of files.. one loads without a problem and other one dosn't update after frame 1. alembic comes from Houdini.. one is very light (working) other is 150mb per 1 frame. but it was working in 2.78c...

I could uploud few frames of it. or better solution i would provide houdini file so you can export alembic by you.. you will just have to click one button and wait few min.

Description of alembic file:
big amount of cylinders, basicly it is carpet, that interacts with sphere that is rolling on it. (simple mesh, no curves)

New thing i just discovered if i del first frame of alembic file, and basicly load alembic from frame 2-60 it loads without a problem, the bug happens only if i do load from 1-60.. i will uploud first 2 frames.

//new edit. So seams like the 1 frame of alembic is sort of corupted.. altho once i load it from 2-60 frames and later i will copy that frame to folder where are other frames. so it is back 1-60.. and just in blender go to frame 1 it will load all without a problem wird.
