Question Blank public fields left in script can cause unusual issues

Hi,

Hope you can help,

Noticed an unusual issue or may be normal and simply my lack of knowledge. Basically I have a player health script with some dialogue elements attached and access to other levels. The player health script is used through out the game in each scene, same health script, so at times part of the script may not even be relevant to a level. If a level does not require a dialogue and these a blank space in the inspector public field area, I some times get unusual errors like game freezes level changes etc. However having filled this blank field with empty game objects or empty text mesh pro the problem is 100% gone. The condition set for changing level is if player makes contact with an active portal (which happens after so many enemies have been destroyed). I have built the game almost finished just making sure its working as best as it can. Just curious to why this is or if it would be better to generate new player health script customised to each scene? Any ideas?

 

Show your code.

 

Please Ignore Just checked through realised I have duplicate scene change should be fine now all good.
