[2.2.13] Rock Spawners produce a warning upon level load

This is the warning in question:
WARNING: P_WriteConstant has been called for Mapthing <number goes here>, this level is vulnerable to context drift if -writetextmap is used.

replying here, because i have the same issue, is there any way to fix it?

In hindsight, it was really dumb to post this as a bug report; this isn't actually a bug since it's just a warning. What actually happened is that I was trying to report something else that I thought was a bug, then I found out that it wasn't a bug and tried to delete this thread, but there was no option to delete it, so I thought I should use this to say something might belong in this sub-forum. And so this thread was embarrassingly left here.

even if it isnt an error it still leaves its mark on the console and that just feels wrong
