Couldn't mount levels from the user directory '/home/web_user/.local/share/supertux2/' to PhysFS searchpath: not found

[enderandrew]

SuperTux v0.6.3-1056-g169decf38 WASM
Debian Unstable x86_64: (details about your kernel, operating system, or distribution)

Expected behavior

Unsure. Does this error suggest there would be persisted storage for add-ons or profile saves that isn't working?

Actual behavior

VM111:79 [WARNING] /home/runner/work/supertux/supertux/src/supertux/main.cpp:287 Couldn't mount levels from the user directory '/home/web_user/.local/share/supertux2/' to PhysFS searchpath: not found

Steps to reproduce actual behavior

Console / Developer mode starting the game in WASM in Chrome and Edge

• I verified this isn't a discussion, but an actual issue ─ that is, the game did something not intended such as crashing or giving error messages.
• This report only includes details about one (1) issue, feature request or topic.
• If I make a mistake while submitting this report I will use the edit feature instead of closing this issue and opening a new one.
• This issue is not about wrong translations (use Transifex for those), or anything unsupported (e.g. third-party add-ons).

It's not an error, it's a warning. It appears because no levels have been created or modified yet.

To not confuse users with developer mode on, I believe this warning can be prevented in such case, by checking whether that directory exists before attempting to PHYSFS_mount() it (src/supertux/main.cpp:285).
