"Accessor[9] memory: Value[0] is out of bounds 30613. (Parameter 'memory')" during glTF export in HL:A

Describe the bug

When I try to Decompile & export I get the error below on several assets for Half-Life: Alyx:

Reference file in a Valve game(Half-Life: Alyx)

Files that did not work when tried:

models/creatures/strider/combine_strider.vmdl_c
models/architecture/backdrop/building_ornate_01.vmdl_c
models/architecture/backdrop/building_ornate_02.vmdl_c
models/creatures/combine_helicopter/combine_helicopter.vmdl_c
models/creatures/combine_dropship/dropship.vmdl_c

Expected behavior

Other models in models/architecture/backdrop exported correctly and were successfully loaded into houdini(including textures) for example:

models/architecture/backdrop/backdrop_building_c17_low01a.vmdl_c
models/architecture/backdrop/backdrop_building_c17_low01b.vmdl_c
models/architecture/backdrop/backdrop_building_c17_low02a.vmdl_c

Version info

[03:25:27.278] VRF v0.1.3.1215 on Windows 10 on AMD 2990wx CPU( not sure if that matters) Latest build and this build appeared to be the same at the time of testing.

Additional context

[Cig0073]

models/props_combine/citadel/citadel_static.vmdl_c The Citadel model also gives the same error.

[xPaw]

Should be fixed on master now.

Still getting an error when I try to export combine_strider.

One or more errors occurred. (Accessor[27] memory: Value[24458] is out of bounds 49716. (Parameter 'memory'))

I open the gui app, point to the paks, right click on combine_strider.vmdl_c, and choose decompile and export.

Using unstable build from appVeyor downloaded today.

Can confirm.

Happens in Dota 2 as well:

Try latest unstable build, it should work now. (minus the dropship model)
