Platform issue in CATACOMBES ROUGES appearing out of nowhere (Room 16967)

[aquaMat]

While going thru all my custom mansions during the

preparation for HD-conversion - process

I discovered an issue with a moving platform in
LES CATACOMBES ROUGES (Room 16967)
that has certainly NOT been there before and is - as you can tell by the screenshot below - not programmed to happen as it does.

WHAT HAPPENS?
The moving platform (hidden behind the skeletons; see screenshot) is normally triggered by a footswitch when Jack arrives through the passage to the left. He can then take the platform to reach the vine.... then he's able to climb the vine into another room, and normally when he gets back to this room, the platform is still operating, allowing him to re-access the leftmost passage again.

Well, not anymore!
When I played it a few days ago - each time I had Jack leave and re-enter this room the moving platform was OFF again.... so Jack was kinda stuck on the vine... which is not very helpful as far as game progression is concerned.

On the screenshot you can see how the switch activating the platform is programmed, and

Switch can be used only once

is still unchecked, as it always has been - and as it is supposed to be, in order for the platform to keep moving.

Question:
I remember that Vern has made some

improvements

concerning platforms and that in the recent past there have been issues in other mansions caused by those

improvements

.... but I don't remember the details.
Could this have something to do with the situation here ??

Any ideas, anyone?

How about ticking the first option?

This is a new one. I wasn't aware of this - I don't remember it reported during testing, either.

I was one of those who tested the mansion and it worked then. Doesn't now when I replay the mansion (There must be others thing not working either as I am having troubles, but I'll wait to report as it can be just me)

aquaMat,

  I just went through and did a few tests in the old game. The behavior is the same. I think the dialog window is the problem: it's slightly misleading. It looks like the default behavior is for it to be reset when Jack leaves the screen, which makes the grayed out option seem very odd to me.

brell is right. All you have to do is enable

Switch can be used only once unless reset

and it stays on indefinitely.

Thanks, Rob, Rose & Brell !

Though I remember having often done that (checking the first option) in similar situations (in other mansions, other rooms), I did not here, probably because I was thinking that - as long as the first option is unchecked, the

sub option

remains grayed-out - resulting in the platform never stopping (simply because the switch can't be re-set).

Probably you are right (I haven't tried it yet) and checking the first option solves the problem.... the question remains though: why is the behavior of the platform suddenly different from how it used to be - even if I never changed anything in the programming. In fact I haven't touched the mansion at all for ages... !?!
That's why I asked if that could have something to do with some changes/improvements Vern has made to platform and/or switch behavior?

However, you are right about the generally misleading nature of those checkboxes (description):  I remember very vividly how I frustratingly sweated over the programming of a vaguely similar scenario in JUMP! where the sprites just NEVER behaved how I wanted them to, no matter what combination of checkboxes / programming I tried.  Can't remember how I ultimately solved it though... (but it wasn't a directly comparable situation anyway).

Thanks so far, I'll certainly give it a try.
