Re-checked the alignment and found a slight twist on the bottom limb. The twist was mid-limb so it wasn't too hard to clamp it down using some shims and heat it up again. This poor piece of wood has taken a lot abuse, that's for sure. The alignment looks a lot better now, but we'll see how long it lasts. Decided to do padauk overlays (because I like the reddish contrast with the hackberry) first before I start the tillering process again. I've left plenty of overlay wood for final reduction, rounding of the tips, and cutting the nocks. Jury is still out on padauk as overlay material, in my opinion.
