Confirmed - cause found, patch not written yet.

The Guild tab draws the wrong artwork nodes with hand-invented geometry: the member row art with its baked NAME/JOB/LV/TITLE column rules is never drawn, and the selection-highlight plate is used as the row instead. Also: this is really three jobs - Guild tab, Party tab, and a Create Guild Emblem window that does not exist at all. Worth splitting.

Moving it out of OPEN so the list reflects reality: this one is pinned down to exact files and lines, so what is left is writing and testing the change, not working out what is wrong.

Fixed in 3b8f5920.

Cause: the user list and guild windows were built by measuring the background image and eyeballing the strips stacked on it, and the code never looked at those strips' transparency. That one omission is the whole bug.

The real member-row sprite (guildinfo3, 281x18) is almost entirely transparent - it has opaque columns at 0, 96, 165, 205 and 280, and those five lines ARE the NAME | JOB | LV | TITLE grid. It was referenced nowhere. What got drawn instead was guildinfo6, which is 282x20 and 95% solid white: that is the plate that goes UNDER the selected row. So every row rendered as a solid white block and the window had no column separators at all. The party tab had the same mistake.

The column positions followed from the same misreading. The header art bakes its labels starting at x 15/111/179/219; the code used 18/114/182/222 - 3px right of every one - and clipped each cell wide enough to run straight through the separator to its right.

Fix: both lists draw their real row sprite; guildinfo6 is demoted to the selection plate it actually is, so the guild list gained a selected row - which is what MAP and WHISPER act on, matching v83 rather than 'whatever is first'. Every cell now starts on its baked label and stops short of the next rule. Party gets its own positions and correctly has no TITLE column.

Retest against your screenshots: column lines, header alignment, and clicking a row to select it.
