Placing light sources seem to cause a memory leak
Steps to Reproduce:
Start placing a bunch of torches underwater.
Notice that RAM fills up more than without placing them.
Observed Results:
The RAM fills up more with placement of light sources than without it.
Expected Results:
The RAM shouldn't fill up more with placement of light sources than without it.
That's not what a memory leak is; only if the memory is used and never released is it a leak. Placing lha light source is expected to use more memory than a normal block as the surrounding area needs to get lit up as a result.
