(svn r20593) -Fix: (rlongago, r20547): long ago the service interval was int16, after which is got converted to Date except in the order backup. Much later I copied the savegame snippets from a vehicle and applied that on the order backup. Presto, reading/writing 32 bits (of Date) into 16 bits of ancient style service interval. That would then "spoil" the name pointer and that eventually crashes OpenTTD as it's likely to be an invalid pointer.
