i don't know what ERAHelpers.h is, it's not at all a part of the plugin, im not sure whats causing this but its something on your end.
EDIT, oversight on my part, there is something which causes this to appear in r-170, i wasn't getting it in r-168. ill have to investigate but it doesn't seem to be affecting anything since my test files are working fine in 170 when the alert was ignored.
