This action (open once and stay opened) is without any purpose and can be replaced without any problem with the action 61 or 115: "SR" (door open stay).
Same thing for the actions attached to a key (action 32, 33 and 34), all having their repeatable version (99, 134 and 136)
So, I suggest to check the maps with the engine and to replace the actions with the repeatable version.
The latest example, for me, is the pwad that I'm actually debugging: "EarthZd" (the Zdoom version of Earth By Roger Ritenour). On Map01, the linedef 385 had the action 33 (D1 (door red) open stay). This door should stay opened, but I found it closed when I came back, and, of course, I had to use a cheat to bypass it. It was so simple and obvious to change its action from 33 to 134 !!!
There was no purpose at all to use the action once instead of the repeatable version.
Our mondial database of pwads is full of bugged maps thanks to this faultive action.
Yes, I know: there is a cheat... But, what a pity to use a cheat to be able to play!!!!
What do you think about my idea?
Have I forgotten an important aspect, not allowing to do it?
If I forgot an important point, I suggest to add a cvar: "OS" (open special). Once used, it would allow to open all the doors having such a faultive attached action, when you are very sure that you are in front of a bug.
For example, most of the time, it's the key "Spacebar" which is used to open a door. I suggest to add a special action, available with another key to configure separately, so that we will have 2 keys to use: one for the normal door, and one when we are in front of an obvious bug.
I hope to be clear enough...
