Figured out what was wrong in my case. Had some free time after work and decided to tinker a bit in my project.
Turned out after updating, I forgot to set up the Event Template Settings of the necessary events. Code was working as intended, I was the one who derped.. lol
For anyone reading this comment and has the same issue, go to [Plugin Manager -> VisuMZ_1_EventsMoveCore -> Event Template Settings -> Event Template List]. Updating the plugin deletes this setting. In Event Template List , just adding new entries with all needed events does the job.
Anyways, can confirm that even after updating Visustella's plugins, project works as intended :)
