Type of Bug: Portal in B4 randomly not working.
Description: 3/4 the way through B4 there is a section with a spiked wall closing in on you. You are to fall down conveyor, strike vent cover until open, use vent portal, fall into area behind spiked wall, bring wondroid to portal, carry wondroid and use portal again.
Issue: In at least half of my runs through this JQ the vent portal does not work, I press up and do not teleport to upper left platform. Spike wall kills me, I restart from checkpoint walk back to area, portal still does not work.
It is not a huge issue for the first save of the day, as I can keep restarting until it until it randomly does work, but this bug has caused me to lose a lot of visitor ID badges, extending the amount of time it takes me to complete S1 from four days to as many as eight days, as I am unable to complete a second JQ due to the portal not working.
I tried restarting the maplestory, restarting the computer and various other methods of alleviating the issue. None of these have worked consistently (meaning the bug seems random, so its difficult to tell if these actions are the reason it worked the following time).
Character name: All mules used so far have experienced this bug at some point, but the one I am currently trying to complete is on Atashì
Character level: My characters range from 140 to 242, has happened on multiple chars so unsure, Atashì is currently 163
Character job: NL, Kanna, PF, Lumi, other Kanna and a couple others have all experienced the bug at some point.
World name: Reboot
Date and time of the incident: A lot, but most recent one was a few minutes ago, so about 4:45-5am CST 2/12/20
