My Test mod contains

modded class ItemBase {}

if i start my Workbench 1.30m exp with:

start "Workbench" /D "C:\Program Files (x86)\Steam\steamapps\common\DayZ Exp" "C:\Program Files (x86)\Steam\steamapps\common\DayZ Experimental Tools\Bin\Workbench\workbenchApp.exe" "-mod=MyTestMod;"

I got an compile error unkonwn type ItemBase

Same steps are working in 1.29.x version

• Create a simple mod,

• override ItemBase

• make a sim link into C:\Program Files (x86)\Steam\steamapps\common\DayZ Exp for that unpacked mod content to root dir of dayz exp

• start workbench with on cmd with:

  start "Workbench" /D "C:\Program Files (x86)\Steam\steamapps\common\DayZ Exp" "C:\Program Files (x86)\Steam\steamapps\common\DayZ Experimental Tools\Bin\Workbench\workbenchApp.exe" "-mod=MyTestMod;"

Dayz Classes will detected.
