Hey! I didn't find any issues; tests showed that the supercard opens all three types of security doors. Third-party plugins might be interfering—do you have any other plugins related to security doors? If possible, please disable them to test

I haven't installed any other similar plugins. This super card sometimes opens and sometimes doesn't. You can test it a few more times.

"These are the two card-related plugins. But one thing is: everything was normal before version 1.3.4. After upgrading to 1.3.5, I didn't add any other related plugins, yet this problem appeared right after the update."

After extensive testing with various numbers and types of dungeons, I’ve concluded that the SuperCard works flawlessly. How often does this happen for you? Could you make a short video showing the SuperCard failing to work? You might be trying to use the card on an old structure that is no longer an active dungeon; this can sometimes happen under certain conditions.

Also, try testing without these plugins:

"Did you test the Red Card room? The main issue is that the Red Card room frequently has problems and can't be opened. The Green Card and Blue Card rooms are basically normal, though occasionally they can't be opened either."

Yes, of course, I checked all types of security doors. I paid special attention to the red ones
