Do you have link to test?

@caiiiycuk sorry I don't have. It happened in one of my users.

I think myabe this error is related with the saves in indexedDB? Because he said he saved the game in the 49th round, and it will throw this error every time in the 50th round.

Is it because the save in the indexedDB is too large? There was another user mentioned a similar error about 2-3 months ago, which happened in the same game level and around 50 rounds

Nope, it’s not related to saves. The problem is in game. I need the game and save on 49 level to reproduce and fix Пн, 5 сент. 2022 г. в 12:16, Ziiven ***@***.***>:

@caiiiycuk I have asked that user to keep the save. Could you tell me how to export the saves from browser?

Alexander Guryanov · Answer 6 · Mon Sep 05 2022 20:35:10 GMT+0800 (China Standard Time)

If you use logged integration, then you can find download button in js-dos settings. Btw, maybe you can pass this turns on PC?

He said the game freeze after he end the player's turn, no matter what he did. Anyway I will upload the game save as soon as he give it to me.

Alexander Guryanov · Answer 8 · Mon Sep 05 2022 22:45:43 GMT+0800 (China Standard Time)

Which game we are talking about?

Ziiven · Answer 9 · Tue Sep 06 2022 07:35:40 GMT+0800 (China Standard Time)

The game is called "Flame Dragon 2". The game bundle is here: https://doszone-uploads.s3.dualstack.eu-central-1.amazonaws.com/personal-v2/studio/dkkpr/bundle.jsdos

However I found out I didn't use logged integration. Is it ok if I exported the game save as arrayBuffer and converted it to base64? You can convert it back to arrayBuffer using this function:

function _base64ToArrayBuffer(base64) {
        let binary_string = window.atob(base64);
        let len = binary_string.length;
        let bytes = new Uint8Array(len);
        for (let i = 0; i < len; i++) {
            bytes[i] = binary_string.charCodeAt(i);
        }
        return bytes.buffer;
    }

base64ArrayBuffer.txt

Just tried the save myself, it will 100% trigger the error even the player don't do anything in that round

When you enter the game you can do the following steps to reproduce:

in the main menu select "continue"
once the game loaded, use the arrow key to move the selector to a grid that without any NPC
press "space" key to popup a option menu, select "end" at the bottom by using the arrow key
confirm end turn by press "space" key
error triggered

@caiiiycuk Just confirmed that this issue is not related to the jsdos. It is something that in the game itself (it set a maximum turns of 50, and will force the game to stop when reach 50). So please close this issue :)

Interesting, thanks! I will keep it open, cause I still want to look into.
