They are very slow and cause the game to crush often, unable to package the game without errors, while running frontend automatic check on the blueprints it just hang .
I really need theme functioning like, yesterday 
please anyoneā¦
You will be hard stretched to get people to download, install and review each and every node of your work, There must be errors or warnings along the way that your missing/ignoring or do they compile perfectly?
Why donāt you try putting them in a new project and testing that, also if your using Event Tick a lot then its going to be process heavy, Perhaps posting pictures of a set piece of code will help give us an idea,
I personally donāt have the time to download install and check your Blueprints, but maybe Epic will
You would have a better luck if you tell us what errors you are getting and post screenshots of your BPās.
Only need to put My_BluePrint folder in the content folderā¦
Iāv tried to isolate the problem, made new blank projects with it, tried some stuff, itās like something is bugged over thereā¦ The blueprint works, when i package the game it gives me errors while i try to run the packaged game :
But besides that, it works perfectly ( When i change something in the blueprint, i save, quit editor, re enter, and it gets compiled while re opening the editor. if i try to compile right away the editor will crash to desktop ).
I tried downloading your Blueprints, I canāt even open them.
What version of the editor have you made them in?
I thought Iād take a look. First thing is that the all the BPās are a mess. Looks like a miss match of stuff Iāve seen through out the forums. I get compile error from the āMyHUDā and āMyControllerā so Iām not actually able to play the game. If you truely want some help I would advise you to go through each and every BP and clean them all up and commenting along the way. You may even end up fixing your issue.
As I look through other BPās I find thereās a compile error is most of them. Hereās a screenshot with the most common issues I find in most BPās. Iām not sure if it just happens to be the version you uploaded but either way each BP is a mess of wires with no idea of what each bit is supposed to do. Remember to make functions & macros for bit that would be used multiple times.
from pattymās example it seems that you have some sort of dependency involved, I run into this before where if you compile one BP, another BP got messed up when they use cast/class related functions.
And if you then just save and restart, it will look exactly like this.(thus require compile blueprints and then compile this messed up ones after choosing/connect the class/node again.)
This was my question on answer hub quite a while ago, but I think it sort of apply to your situation.

so yeah, this is rare if you handle your dependency well, but it will show up when you are in fast prototyping mode and doesnāt think through carefully.
