[1.4.8] Cannot open non-orcs save file

[Zeyphor]

When I attempt to load a save file that doesn't have the orcs campaign installed on it, I get this LUA error at "100%":
Lua Error: /engine/Particles.lua:68: cannot open /data/gfx/particles/dummy.lua: No error
At [C]:-1
At [C]:-1 error
At /engine/Particles.lua:68 loaded
At /engine/Savefile.lua:493 loadWorld

At /engine/utils.lua:2221 showMainMenu
At /engine/init.lua:165
At [C]:-1 dofile
At /loader/init.lua:217

the LUA error does not show up ingame, and was retrieved from te4log.txt

after getting a brand new copy of ToME, I got this LUA error when trying to go to the character creation screen after copying over T-engine/4.0/tome but by that point i hadnt installed embers or ashes yet

after installing the addons I am able to access the character creation screen, but I still cannot load a non-orcs save file that existed before the orcs campaign was released, and I still get this LUA error in te4log.txt
