Thanks enigmaX - found it. The ladder at the top of Line 3 Construction Site B1 <Area 2> ends in a narrow 60px-deep slot, and the ledge with the exit portal starts right at the top of its wall. When the jump physics changed on 09-24, the air stopped carrying the walking push, and our wall collision was also holding your character 6px away from every wall. Together that meant you could never drift those last 6px over the corner before falling back down. The real client stops you right on the wall line, so the moment your feet clear the ledge you're over it. That's what we do now too. Tested on this exact spot: holding right and jumping, or jumping straight up at the wall and then pressing right, both land you on the portal ledge. The fix is pushed but not in the live build yet - it goes out with the next update. I'll mark it Fixed once you've confirmed Shumi's Coin works for you.

Update (grounded ledges): on top of the pit-jump fix, we found a second, related problem — walking straight into a ledge on flat/town ground could push you backward, bounce you, and even shove you through the wall and drop you through the level. Cause: the body stopped exactly on the wall line (correct, matches the real client), but our ground check briefly lost the floor one pixel past a ledge's edge and fell back to an old wall routine that kicked the body ~15px back. Fixed so the body keeps the floor at a wall corner and stops cleanly on the line. Live now (deployed release 20260926T193120Z). Worth re-testing: walk (not jump) straight into raised ledges/steps in town maps like New Leaf City — you should stop dead at the wall, never bounce back or fall through; jumping onto a low ledge and up out of pits should still work.

Closing this as fixed. Both parts have been live since the 26 September update: the pit jump at the top of Line 3 Construction Site B1 <Area 2> now carries you over the ledge onto the portal, and walking into raised ledges in town no longer bounces you back or drops you through the floor. We tested the exact spot from your screenshot, holding right while jumping and jumping straight up and then pressing right, and both land on the portal ledge. If Shumi's Coin still gives you trouble, or any ledge still pushes you back, reply here and we'll reopen it. Thanks for the clear report, enigmaX!
