Signs error

[Martelprod]

I noticed some jpegs in Any/Advertisement are sometimes modified by the game and became unreadable by players and me.

Locators are working fine (links work in browsers). Jpegs hosted aren't affected by this modification.

Why this happens?
How do I can avoid this ?
Any way to prevent changes of skins folder ?

Hi Martel,

Could you please provide us with a sign which doesn't work well?

Hi Alinoa,

I sent you 2 files with locs.

We investigated the issue a little bit and found out that the issue comes for signs that have been hosted on different services throughout the year.

In particular, we believe that when a map is saved, MP doesn't necessarily use the locator in the player's Skins/Any/Advertisement folder, but uses an old locator from the game cache instead. If that locator happens to point to a non-existant file, the sign appears black ingame and the sign in the player's Skins/Any/Advertisement folder is replaced by a black image.

Potential steps on how to reproduce (a bit complicated but well...):
- Make a sign named TestSignLocator.jpg in Skins/Any/Advertisement
- Host it on a service A
- Create a locator for TestSignLocator.jpg based on service A, put it in Skins/Any/Advertisement
- Make a map using TestSignLocator.jpg
- Play the map online so that MP cache is set up
- Delete TestSignLocator.jpg from service A
- Host TestSignLocator.jpg on a service B
- Replace the locator for TestSignLocator.jpg in Skins/Any/Advertisement so that it points to service B
- Make a map using TestSignLocator.jpg
- Using GBXdump, check the locator for TestSignLocator.jpg. It might point to service A instead.
