Xgen Hair not rendering, xgmsplineCache repathing not supported?

i sent a scene to the farm and im missing some hair from my render

the hair on the eyebrows is there however the scalp hair is not. I beleive this is because there is an alembic cache piped into the scalp hair whereas the eyebrows have no such cache. The alembic file itself is not piped in through a standard maya abc node. it uses something called xgmsplineCache

perhaps the missing hair is totally unrealated to the cache but this is my best guess.
returned from AWS:


What im expecting:

The Node

It appears the problem is that repathing is not supported on that node. I worked around this by plugging a standard alembic file into the “filname” input of the xgmsplinecache
