How to replace message in BubbleChat?

[Roldstred]

I’m making ingame language system and for that I sometimes need to replace players messages LOCALLY.

To do that I copied “BubbleChat” Core LocalScript from PlayerScripts folder and replaced some strings with my code and that was meant to work but somewhy script is not working as i expected.

P.S: im using legacy chat cuz new one is NOT editable at all

To find out where exactly code go in wrong way I put print command at almost every line of code that is about sending or receiving messages from players:

If you check whole script there is bunch of print commands AND none of them working except the one at line 630 of the script:

Ofcourse I tried putting the script in ChatService too, same effect.
And at first I made custom chat but then failed with sizing bubble gui and decided to get back on Core Roblox stuff.

I think this might be cause this script isnt the one controlling player’s chat and im just dumb asf

Output:

I forgot to mention the part where I replace messages, can send it if needed but dont think its too important cuz code doesnt even run to that place

Hope yall can help me

I made brand new place and moved the script in here, then removed line 631 and it started working.
