Getting this error after updating asm:

[UPDATER] Started processing mod 1 of 5.
[UPDATER] Mod 715028562.
[UPDATER] The Volcano.

[UPDATER] Skipping mod download - mod cache has the latest version.
[UPDATER] Forcing mod copy - mod is not versioned.
[UPDATER] Started mod copy.
....[UPDATER] ***********************
[UPDATER] ERROR: Failed mod copy.
Bad state (oversubscribed literal/length tree)
[UPDATER] ***********************
[UPDATER] Finished processing mod 715028562.

Not sure what this error is. I tried deleting the mod manually from both server and client...and re-downloading. I tried deleting Steam cmd and letting asm re-install it. All other mods update fine...suggestions?
