[High] Warehouse crash #17
Description
Some users reported broken savegames after changing to the crystal world (3rd).
"rand" found out that warehouse nesting could be the the source of this problem.
It is possible to put warehouses with content into a warehouse. This warehouse can also be stored in another warehouse...
After unfolding these warehouses, the savegame was loadable.
Try to reproduce this behaviour and fix that by suppressing warehouses to store warehouses.
