ACE installation skipped for part of mutable content

[rafineria123]

Prehistory:

AEMaaCS - latest version
AC Tool - v3.0.10

Problem description:

When I deploy new build to environment "startup_hook_image_build" is triggered and AC Tool installs ACLs from config.yaml (as expected) as shown in this example:

There are no errors during the installation of ACLs however most of mutable content is skipped during the installation.
Any path at or below /content/rafineria123 will be skipped(log example - 11:46:12.185: Skipped installing privileges/actions for non existing path: /content/rafineria123/feedback).
/content/users and /content/usergenerated are updated correctly(log example - 11:46:12.200: Update result at path /content/users: O=1 N=0 D=0 A=2)

Most of configurations in config.yaml are set to path /content/rafineria123 or below and i cannot find a reason why these paths are considered "non-existent" during startup_hook_image_build installation of ACLs.

When I run the install from console(/mnt/overlay/netcentric/actool/content/overview.html/actool) it works correctly and no paths are skipped. It also works correctly when triggered by "startup_hook"(without the "image_build" suffix).

I have not been able to find the root cause of this problem - my wild guess is one of these two:

1. Content is not fully installed on publish pod and startup_hook_image_build is triggered too early,
2. actool-service does not have the correct permissions to access /content/rafineria123 - but if this is true, then the console install should not work either.

Any chance you could tell me where to look for the cause of this problem?
