got this when opening a requester chest building electric engines on fulgora

I will need a bit more information about this:

• Are you using any other mods?
• Is anything there connected to circuits? Specifically the chest, the inserter, and assembler.
• Are there any quality items/ingredients there?
• Are there non-item signals on the requester chest logistic group?

If you could upload your save somewhere that would be the best. If not, you can send me the save over the official Factorio discord, using the same username.

Otherwise, please upload a screenshot of how the requester chest looks without FilterHelper enabled.

I think I found the issue, and it's relating to non-item requests in the logistic group. Will be fixed for the next version, but I want to confirm it is the issue you were seeing.

A screenshot of your requester chest open without the mod (which crashes with the mod) would be appreciated.

Probably fixed in the current version. Let me know if it's still an issue.

Are you using any other mods?

Yes a decent amount but mostly qol and stuff.

Is anything there connected to circuits? Specifically the chest, the inserter, and assembler.

Probably not.

Are there any quality items/ingredients there?

No I dont think there were

Are there non-item signals on the requester chest logistic group?

Since Engine Require Lube and the new Paramterised Blueprint auto fill Liquids into Requester Chest this was probably it.

A screenshot of your requester chest open without the mod (which crashes with the mod) would be appreciated.

I dont remeber which one it was. I will enable your mod and if it happens again collect more info.

Lube would indeed crash it like that, so that's fixed.

Let me know if it still crashes or not!
