minetest-mod-tsm_pyramids/mummy.lua
general 6b53a21c96 backguard compatibility for 4.X on translator and noisebuffer loading 
* the wrokaround is done waithing until mod loads using minetest.after,
 at older engines we only can callit one time at load, but now the error
 generates in other place..  check for more elaborate solution
