I have noticed a few issues with the guide.
Square Tower Level 1 – The picture indicates rustic stone floors, but the parts list calls out rustic wooden floors. I think the product name in the table needs to change
Square Tower Level 2 – Sequence #5 is indicated as part of the Alchemist Guild Expansion pack, but the file name is “A-Wall-Schist-v0.2”. Seq #8 has the same file name but references the Schist Walls set. My guess here is that Seq #5 has an incorrect file name.
