[Experimental EXE] CH8 Crash when pressing "Read again" button at Bern's game

[drojf]

Bug Information

Describe the bug: During Bern's game, the game crashes when pressing "Read again" for a user

To reproduce: Click "Read again" during bern's game

Expected behavior: The game should show 6 buttons for you to choose which subsection to start from

Install Information

The game: You should only report Umineko Answer issues in this repository (use the question arc repo for the question arcs

The mod variant: ADV

I installed the patch: ???

I bought the game at: ???

Mod Install Date: ???

I couldn't reproduce the crash on my own computer, but there does look to be some funky stuff to do with the buttons during bern's game. I feel like there may have been a report related to this in the past, but it seems very infrequent (this user also has more crashes than other users)

We had this reported again by @orian34. They are using:

• Experimental Exe (I think...because they have the crash when you end fasforwarding which only occurs for experimental exe)
• Experimental script

unsure why but the game always crashes if you try to reread Bern's game in ep8
Yeah. The reread button just crashes.
Also fastforward tends to crash the instant I stop doing it, unless it is stopped by a menu

I'm not sure what changed on my system, but on the experimental exe I can now reproduce the game crashing...

maybe earlier I didn't realize it had to do with the experimental exe, so I was testing on the normal exe which didn't have the issue.

The reproduction instructions are (although I only did some of the following instructions, I'm just stating my setup):

1. Install Umineko Answer (from steam, gog, mangagamer etc.)
2. Install 07th-mod Answer arcs
3. Enable ADV mode (the default). Not sure if this is necessary but I did on ADV mode
4. Ensure the game is completed (unlock all chapters via the unlock buttons in main menu)
5. Click "Start"
6. Click "'Episode 8"
7. Click "Cast the spell"
8. Click "Challenging Bern"
9. Click "Read Again" (which is meant to put you back in the story segment, which is the same as if you clicked "The Bern Puzzle" in the chapter select menu)
10. On the experimental EXE, the game will crash.
    • On the normal EXE, the game doesn't crash.

Please note I also made an issue in the ponscripter-fork repo (the experimental exe repo): 07th-mod/ponscripter-fork#25

[drojf]

Pushed a workaround for this 2e9e1f7 where I change the order of the cl a,0 command. For more details see 07th-mod/ponscripter-fork#25 (comment), but the issue seems to be if you do a cl a,0 to clear a standing sprite before btnwait2 without a print in-between.

Note: in the commits, I accidentally tagged #25 instead of this issue #89
