[Other] Flags are reset after saving

[ipokemoney]

I've been creating a hacked version of Pokemon FireRed using PKSV and Advance Map.
I encountered an issue regarding save.

I set a certain flag (let's just call it 0xA here), and then I saved.
After resetting the device, I continued from my save point.
Then, I found out that the flag 0xA is not set anymore.

I'm new to Pokemom hacking, so I might not be understanding some things fully. Can somebody explain why this happens and how I can fix it?

Could you show us an example of your script or which flag you used in particular? Not all flags are safe to use and you might have accidentally chosen one of them.

Actually there are a load of temporary flags in the game. I would only use the ones specifically used in the game for non-ingame features.

Flags 0x200 to 0x2FF are safe to use, and non-temporary (according to DavidJCobb's research, which I would trust.)

I'm using flags starting from 0xAAA0.
I'll try replacing my flags with the ones between 0x200 ~ 0x2FF.
Does it also mean that I have just 256 permanent flags that I can use safely in the game?

Thank you so much, the flags don't reset themselves now.
Are there any other safe flags to use?
