please report this as a new bug!

This fix (as of g3.8pre-180-ga2065cae4) creates the following problem with the example WAD (steve_flashlight_2018.02.10.pk7 from the OP): after toggling the flashlight once, saving the game will create another copy of the light in the same place where the light actor was last positioned. Saving the game repeatedly seems to create more and more lights, ad infinitum. Turning the flashlight on again will make all these lights move together as one. Loading the saved game will make all lights but one go away; one light always remains regardless of whether the flashlight was turned on or off when the game was saved.

same as the other one.

When a save game is loaded, dynamic light actors have lights [url=https://github.com/coelckers/gzdoom/blob/6f6dc60e2b7f74a448b8884b75ea940615253734/src/g_shared/a_dynlight.cpp#L861]reattached[/url] to them, but these lights are not reactivated. That's why the light disappears.

An obvious solution would be to check if the dynamic light actor has the DORMANT flag unset and activate the light in this case. However, this flag can be changed on the script side at any time, so it's not foolproof.

[b]Edit:[/b] It seems that RecreateAllAttachedLights is called not only when the game is loaded, but also when it is saved. I'm not sure if I understand the need for this, so I won't provide a PR here. The cause of the problem is more or less evident, anyway.

Same mod as before. Turn on the flashlight, save the game, then load the game. The spotlight would disappear.
