Whenever I change an event that's been emitting particles like:

    part_particles_burst(global.ps_vfx, x, bbox_top + 315, PE_MiningDrill_Smoke);

I'm getting error like this

 called from obj_BOSS_MiningDrill:Step_0 [line 36, col 60]
[GMLive][30-05-2026 15:56:40][ERROR] Runtime error: [error] `instance#ref instance 103824(obj_BOSS_MiningDrill)` (instance of obj_BOSS_MiningDrill) does not have a variable `PE_MiningDrill_Smoke`.

This error is persistent, updating a code with similar code %100 gives error. 

You could do a live_constant_add in obj_gmlive’s Create event, like so

live_constant_add("PE_MiningDrill_Smoke", PE_MiningDrill_Smoke);

I’ll need to check if asset_ functions work for particle systems in latest GM.
