Reproduction steps:
1) Open user's attached project
2) Run "Build Android/Build SFxs for Android" in upper menu
3) Go to "dist/android/deptexture/" folder ("dist" folder is outside project folder)
-- Notice that there are only two files: "t_fx01.bundle" and "t_fx01.bundle.manifest"
4) Run "Build Android/Build SFxs for Android" in upper menu once again
5) Go back to "dist/android/deptexture/" folder
-- Notice two additional files were created ("t_fx01_etx_alpha.bundle" and "t_fx01_etx_alpha.bundle.manifest")

Expected result:
All four files should be created after first run of "Build Android/Build SFxs for Android"
