Feature: Debug long-term entity id issues.

[DaanVanYperen]

Option to hold deleted entity ids for X seconds before allowing them to be reused. This helps debugging dangling references that get recycled.

So it would crash on getting an entity by (invalid) id? Have you tried it in practice with some plugin of yours, maybe?

Is this really a common problem? Just curious for the sake of my project, also I'm not making enough games lately.

It would report illegally access to the deleted entity, and report the stack trace of wherever the entity was deleted. Much like the rest of the debug plugin https://github.com/DaanVanYperen/artemis-odb-contrib/wiki/Debugger-Plugin

It's caused by user error when referencing entity ids. @entityid should mitigate it in most cases (assuming junkdog/artemis-odb#574 gets fixed). When it does happen, it can cause all sort of weird bugs and tracing the origin can be really hard.

I still run into it myself ever so often so for me its a worthwhile feature to add to the debug plugin.
