Receiver QU help Wrote:Some of these values may return garbage when checking for predefined seer huts (e.g. number of creatures). You will have to truncate such values to the appropriate size manually.

This means that in some cases these values occupy less than 4 bytes, but QU:R returns all 4 bytes. You can extract the real value either with VR:&(X-1) or VR:%X where X is 2^number of bits. I would guess primary skills, morale and luck occupy 8 bits (or 1 byte), which means X=2^8=256. Don't remember about creatures, probably somewhere between 10 and 16 bits.
