I really can not see any reason for this and now evrything has crawled to a halt as I cant make acid/batteries/plastic etc ...
If anyone can see why this is happening and could point me in the right direction I would be eternally grateful, if you need any more info or more screenies please let me know.
Thanks in advance
Dougal.
EDIT: just to add more info that i thought might help
