Is LightCleaner still necessary?

Server Implementation

Paper

Server Version

1.16.5

Describe the bug

When generating new chunks with a custom template that includes lighting-blocks, the lighting is not updated after the chunk is placed the first time. Instead LightCleaner was advertised in the past.

The problem is, that LightCleaner goes into an infinite loop of calculating light for unloaded chunks and this is costing a lot of performance. The author of that plugin said, that the problem relies elsewhere and it is not his fault, so I wonder where this problem comes from.

To Reproduce

1. Use Template with lighting blocks, for example 'Bridge.template'
2. Generate Chunks
3. See no lighting

Expected behaviour

PlotSquared should handle the lighting itself.

Checklist

• I have included a Plot debugpaste.
• I am using the newest build from https://www.spigotmc.org/resources/77506/ and the issue still persists.

Anything else?

No response

Start by reviewing the Plot Debugpaste and reproducing the issue with the Bridge.template on PlotSquared 6.3.0 and Paper 1.16.5. Trace chunk placement and lighting updates for lighting blocks, then compare the behavior with and without LightCleaner. Done means newly generated chunks receive correct lighting without an infinite loop or major performance cost.
