V0.02 had a potential softlock near the end of level 6, when you reach the garden path. There is a linedef on that path that served as a single use, walk over teleport trigger.
I had originally thought the issue due to a monster being on the teleport destination at the time of crossing said linedef... I completely overlooked the fact that the player should have teleported and simply telefragged said monster had that been the case.
Working under that assumption, I did some work on the area and the problem had seemed completely resolved with the release of V0.03.
However, it has come to my attention, through some feedback, that the issue appears to have returned. The first instance that was reported to me was a playthrough using Project Brutality 3.0. Naturally, I assumed that the issue might be related to that mod.
The second bit of feedback brought it to my attention that the issue was also happening with no other mods active. After a number of tests, it appeared to be happening when the hard option was chosen.
I can only hypothesis that an errant monster was getting to that path and crossing the linedef before the player arrived, using the single use teleport function. However, I was not able to identify which monster was causing the issue, if indeed that was the problem, nor could I pinpoint where it would be coming from.
As such, I have made some minor adjustments to the area, making the teleport linedef repeatable and moving the spot to which you teleport after completing the garden sequence to a location beyond said linedef, so the player won't have to cross it again, once that area has been navigated.
I have updated the download zip with the newly fixed version of the WAD, along with a new copy of the level 6 save, so that it will continue to be useful.
Below is a screencap of the problem area with the fixes in place. For anyone who has encountered this issue, you should be able to re-download the WAD for the fixed version, or if you don't feel like downloading it again, please feel free to noclip through that section. It's right near the end of the level anyways.
For anyone who is just looking to download the WAD for the first time, you should be able to ingore all this completely.
Sorry for any inconvenience this may have caused.
The linedef at the top of the yellow highlighted step was a single use teleport trigger. This has now been changed to repeatable and should now trigger everytime you cross it, teleporting you to the garden on the right and the teleport destination you can just see behind the rock wall.
The yellow highlighted step used to be the teleport destination for the left hand gardens exit teleport. This destination has now been moved to the top of the garden path.
This is to avoid having the player instantly teleported back to the right hand garden, once the whole area has been completed.
I'll post a quick video explaining a bit clearer as I feel this post may be a tad rambling.
