Very bad :(

Is it every time you load a project? Every project?

[pnorman]

Not every time I load a project - I'm not sure if I did a git pull since then, but I think so, so it's not even every time I git pull

[yohanboniface]

humm, I'm not sure how git pull is linked to the issue, can you provide steps to reproduce?

[pnorman]

My guess is git pull changed a bunch of files on Kosmtik. Looking at the error it either removed an image file before the rest of the changes or something similar. I'll see if I can reproduce.

[yohanboniface]

Oh, now I understand why you talk about git pull. It's on the Carto project, not on the kosmtik project, that you run it, right?

I'll see how I can prevent that the project is autoreloaded when more than once file is changed in a very short time.
For your information, you can set autoReload: false in your kosmtik.yml to deactivate autoreload, so you can reload clicking on the reload button (which will be orange when the map has changed), for example:

I'm running with this myself.

(It doesn't fix the initial issue, but that's a workaround that may interest you. Myself I prefer not to have autoreload.)

Yes.

I turn off autoreload sometimes, but across so many machines it's not always off.
