C3 crash randomly when (i think) copying sprites
I can not replicate this, I dont even know what triggers this but it keeps happening regularly in my project and I keep losing progress, thus the report. Regurarly means at least once a day. Usually when I'm drag copying something in my layout. I've attached the error report information.
Attach a .c3p

Expected result
No crash

First affected release:
Latest stables but has been happening for a while, the last 2 stables for sure.

As per the bug report guidelines I'm afraid it's often impossible to investigate issues like this which don't include any sample project or steps to reproduce, as it means there is nothing for us to investigate. However based on the crash message it looks like it might be related to the Instances Bar, so assigning @DiegoScirra to take a look.
Thanks Ashley, there has been similar reports in the Discord. If i can replicate I will post an example but I havent been able to yet.
Are you able to share your project?
The crash suggests the problem has something to do with cloning instances which are inside a folder in the Instances bar. I have tried replicating the problem but haven't been able to, so maybe there is something about a specific folder structure.
@DiegoScirra can I share it privately with you? It’s my full game so I don’t want to open it to everyone. If you got an email I can share it through git and make you a branch (project probably needs some addons). I can reach out on discord if you prefer too.
Oh, it's ok then, it probably won't help much unless it's a specific project that replicates the problem consistently.
I'll keep trying to figure out what the problem is.
Not sure if helpful or not, but another crashlog where i tried to move and copy an item by pressing ctrl. Two items are overlapping each other (same size and position).

I found and fixed a possibly related issues in which setting a hierarchy through the Instances bar left some of the instances involved in an inconsistent state which didn't crash right away, but was prone to do so later on.
That will go out in the next beta, since it's not exactly the same problem this issue will remain open, but maybe it will be gone with the next update.
amazing, thank you @DiegoScirra, hopefully that fixes some situations
Unfortunately trying to fix this introduced the much worse #8576 in r437. The good thing is that one is an easy fix, the bad thing is that it has pretty bad effects. It's probably better to wait for the next beta when that one is sorted out, before looking at this again.
I'll close this now as I was never able to replicate the original issue.
I keep getting these crashes @DiegoScirra @AshleyScirra , I've now moved to the latest stable since my old game is released and it's still happening in my new project. But the error message is different than before. This happened when i tried to add a instance value to a family. What i think happened:
- i added the value first to the instance itself
- realized this was wrong, deleted said value
- clicked on family, clicked on add value
- added the same value
My theory is either the deletion doesn't work properly/fast enough OR it tries adding it twice when i pressed ENTER on my keyboard. I've noticed this sometimes when adding Effects that it adds them twice for no reason, which i've always assumed has been that construct for some reason reads my input twice in a very quick succession:

I'm afraid as per the bug report guidelines it's usually impossible to help unless you file an issue following all the guidelines. That means providing a sample project file and steps to follow to reproduce the problem.
Sadly I can't reproduce it but it's a common occurrence and seems to have something to do with families because it happens when i add values, copy paste instances or even add things to the family.
