Hello, I've happened across a fatal crash relating to this mod. It's been reported previously but it was quite some time ago.

Simply, this mod is causing a crash when attempting to dictate that a workbench's product be brought directly to a named stockpile. I would provide more info but after some testing, I've found that both the dev console and .log file are providing no input relating to the crash.

Since this bug relates to a relatively niche feature within the game, I recorded a short showcase of the crash in action. As shown, it is done on a blank modlist, with only the DLCs, this mod and its requisites.

Thanks for taking the time to create a handy mod for this wonderful game. Keep up the great work!

Other than the crash which I'm sorry about, I'm glad to hear you've gotten something out of my mod. I remember seeing this issue before, someone added an issue entry on my github as well. I really appreciate this video. Exact steps for replicating will be super helpful.
I'll see what I can do about fixing this this weekend I think.

I have played a bit of Dwarf Fortress recently and there's a DF Hack tool that does something fairly similar to my mod. It looks through stockpiles and combines stacks together if possible. I've been thinking about either changing my mod to work that way (combine separate stacks in a stockpile after placement), or maybe implement both options and let users decide between the implementations. The way my mod works today is prone to issues, especially with mods like pick up and haul which modifies hauling behavior in a way that makes the two mods not work well together. Combine after placement has the downside of you needing a few empty slots in a stockpile short term so multiple haulers can still haul to a stockpile at once.. but it shouldn't have as many weird bugs and should be compatible with pick up and haul

Funnily enough, I had been using this mod alongside Pick Up and Haul for pretty much the entire time I've been subscribed. I didn't know about the incompatibility until coming here to report the bug, but uninstalling the mod to avoid the crash for now was simple enough.

I don't know much about the internals of modding, but I can say that your solution requiring multiple empty slots is seems like it'd not be as problematic as it may have been in earlier versions of Rimworld. With shelves being so prevalent in storage setups now - with their multi-slot nature - I've found that I rarely fill up my stockpiles nowadays, even after having uninstalled my stack mods and reverting to vanilla stack sizes.
