Web tool : simulation never goes through

[Critxtth]

Describe the bug

First of all thanks a lot for your work, wowsims is a great app 💕
I've been using your web tool since the begginning of WOTLK and never came accross any issue.
Very recently, I've been trying to sim my chars, but the simulation never ends. It stops in the middle of the iterations, and doesn't show real DPS. I havent touched any settings, and it happens on every class/spec that I try to sim.
I tried different web browsers, private navigation, doesn't fix the problem.
The video of the issue is available here :

To Reproduce
Steps to reproduce the behavior:

1. Go to web tool
2. Select any spec (I tested fire mage, combat rogue, shadow priest)
3. Launch sim
4. See error

Expected behavior
Finish the job and display real DPS

Does the browser console show errors?
Does it still happen if you set the worker count to 0 (the cog button top right, set "Use Multiple CPU Cores" to off)?

• Does the browser console show errors?

Here is he output on the console :

Uncaught (in promise) TypeError: WebAssembly compilation aborted: Network error: Response body loading was aborted
Promise.then
(anonymous) @ sim_worker.js:617

• Does it still happen if you set the worker count to 0 (the cog button top right, set "Use Multiple CPU Cores" to off)?

It seems like it fixes the problem indeed. Mine was set to 4, I turned it off and it worked again. It seems like it works for value = Off, or 2, but doesn't work for the values above.

But thatll do it for me, thanks for your fast answer ! You can close the issue if you want. 👍 💕

Not sure if that is a bug with the site or with your network/browser. But in any case an error like that should be handled and not cause the sim to just get stuck for the user. Therefore this should stay open until that is resolved.

No, that's an actual sim error. Here the lib.wasm isn't loaded so the worker doesn't even do anything, and there's no error handling for that atm. And because of that the concurrency code sends partial work to dysfunctional workers and never gets an error back, so it just gets stuck visually waiting for progress.

Having the same issue after downloading the Local SIM. Even after I deleted it it is still doing it.

@Caldorwow It just gets stuck without showing any error? Could you provide an export link of your settings?
