I've updated the typo's. If someone can provide the IWD scrlev file I'll replace the text in old_scrlev. I don't have IWD installed at the moment.
Also, some of the updated opcodes which list stats that they modify (i.e. such as this one) incorrectly link stat numbers to opcode numbers.
Not going to get updated in this release, perhaps in the next one.
area file structure, container section
The specific text is updated, though there are probably other areas within the IESDP where it's referenced as a point, rect, bounding box, etc. Point them out and I'll update them.
