icon probably not a bug? - TCB demos where I die (0)  
I am currently running the latest Linux version of TCB and am looking at some of my old demos because a friend is playing TCB and I want to remind myself of what some of the rooms were like. I see that in a surprising number of demos I now die quickly. Water skippers seem to be present in all the cases I've noticed so far but this may be a coincidence. I assume this isn't really a bug but searching for "gets himself killed pretty quickly" or "broken demo" doesn't find much on the forums. I guess some change in movement order or similar has caused some of my old demos to fail and this is well-known and routine.

I don't imagine this is interesting enough for anyone to want me to upload any of them but I can if, unexpectedly, it is.

Edited: I've put 5 demos where I die in later messages in this thread. They all have water skippers. However, there are plenty of other water skipper rooms where all is well.

This usually happens when a hold is updated. It can happen when behavior in the engine changes but usually that will not break existing holds.

What rooms are you noticing this in?

A quick look now shows River Dugan 4S1E and 4S4E but I'm pretty sure I've seen at least one other example as well.

Clearly my threshold for "surprising" may be lower than I realised, though maybe any at all should be somewhat surprising.

Edit: 5 rooms found. Demos in later messages.

Abyssian Fortress 1S. water skippers once more.

This is the fifth one. I think "surprising" is starting to seem almost reasonable now.

The former, rather than the latter, I think. I'm using an older version of TCB in 5.0.1, and the two demos I tried from this lot (River Dugan 4S1E and Abyssian Fortress 1S) both worked correctly. That is, the player conquered the room and exited without dying.
Without version numbers/proper changelogs for the main holds, it's hard to tell what has changed when...

It's neither, actually. The latest version of DROD does not invalidate those demos, and nor does the current spider (which should naturally be using the latest version of the hold).

Which possibly points to a bug with the Linux version, which is beyond my ability to test.

I am using the TCB engine to play these since that's where my saves for KDD/JTRH and TCB live. I could try to migrate the TCB save to Gunthro or TSS to see if they _also_ claim these demos are invalid.

Hmm. Exported and imported saves but it won't let me view my own demos because I haven't conquered those rooms. Even though I can restore to those levels now. I have never tried this before so am probably doing it wrong.

That was with TSS. Importing my TCB saves into Gunthro works but it also says the demos are invalid. Or at least the first three I've tried.

Can someone who has TCB installed and conquered investigate this for me?

The above demos all play back fine for me in 3.3.0.96 on Windows and 3.3.1.98 on Linux.
