Gmod Update 160 Not Saving

[Spartan 653]

I recently downloaded the latest update for Gmod 13, 160, and the game won't save. The error in the console comes up as...

ServerLog: Sending save to player Player [1][Glasg0wned]

[ERROR] lua/includes/modules/duplicator.lua:161: attempt to index global 'Tab' (a nil value)
1. Save - lua/includes/modules/duplicator.lua:161
2. CopyEntTable - lua/includes/modules/duplicator.lua:501
3. Copy - lua/includes/modules/duplicator.lua:566
4. CopyEnts - lua/includes/modules/duplicator.lua:597
5. SaveMap - lua/includes/gmsave.lua:81
6. unknown - gamemodes/sandbox/gamemode/save_load.lua:27
7. unknown - lua/includes/modules/concommand.lua:69

I tried using gm_save as well but that brings up the same error. Any advice would be appreciated.

Which map? Does it happen on one map or all?

It seems to have fixed itself now. I think it was just one map.
