When adding or removing any Resource Pack from a world, the game an crash to certain degrees depending on the pack added

If replacing one add-on with another add-on, the game can crash in certain places in that world.

Steps to Reproduce:

1. Get two add-ons

2. Put one on a world

3. Replace the current add-on with another add-on

4. The game crashes in certain places

Expected Result:

The game runs fine, it doesn't crash every 5 minutes.

Note: On Nintendo Switch, the issue is worst, the game just closes instead. This issue is not caused by specific add-ons. It's also not a duplicate of MCPE-180342. The add-ons were from the Marketplace.

If you would like to know the name of the addon replaced, it was the Magic Spells Add-on

Please fix this so I can add Tinkers Construct Lite to my Realm.
