My world editor seems to be refreshing every 15 seconds after the hotfix 0.25.1, any help would be appreciated. --- Post updated ---
Hey, I had this issue, it was caused by a repeating error in the console, once I fixed that repeating error (for me it was a mispathed texture file) then cleared the cache, it stopped refreshing. Can't promise the cause of your problem is identical, but the end result (the refreshing) was exactly the same.
I'm getting the same, but it is on a map mod I'm making, so not vanilla. Haven't checked with a vanilla map. There are Lua errors, but nothing I can fix.
Had the issue again but the cause was a mod popping up LUA errors. Disabling said mod (expectedly) fixed it. Both times, for me, it seems like repeated console messages causes the editor to flash/refresh. The refresh seems to coincide with the console 'scrubbing' its history after too many entries are present.
I use Beam MP and play on Mp on random servers what has mods so can that make my editor do random things. I try that in both of my maps editor refresh itself and the first map didn't have that problem when i made it, uploaded in mods etc..
The mod that was causing issues for me was BeamMP. It was flagging a failure to connect since it hadn't hooked into the game (I launched without using the MP launcher). This could likely be the cause for yourself, too.
