[Unstable] Level editor doesn't spawn the same level/wrecks/beacon as in preview

• [x] I have searched the issue tracker to check if the issue has already been reported.

Description The level layout, wrecks and beacons you see when generating a level in leveleditor aren't the same as what you get once you test it.

It can spawn a different item at a different place entirely

Preview (custom beacon) near center

Testing (regular beacon) on bottom left

Steps to reproduce:

1. Extract in Localmods BeaconCustom1.zip
2. Open in editor and save to make sure it properly enables the beacon
3. Open leveleditor, keep generating until a beacon appears
4. Test the level, the beacon sometimes doesn't match with the one shown in preview

Version Unstable 0.17.7.0
