Description
When attempting to join a server that turns out to be full (after sitting in the join queue), the game does not display the "Server Full" dialog. Instead the scripting VM throws a NULL-pointer exception during the dialog's initialization, freezing on the connecting/loading screen and then crashing to desktop. The crash originates in base-game UI code, not in any mod. In SCR_ServerFullDialog.UpdateDetailIcons(), the widget reference m_wDetailIcon_CrossPlatform is null and is used without a null check. It is reached via SCR_ServerFullDialog.Init() from JoinProcess_OnJoinFail().
Stack trace:
Reason: NULL pointer to instance. Variable 'm_wDetailIcon_CrossPlatform'
Class: 'SCR_ServerFullDialog'
Function: 'UpdateDetailIcons'
scripts/Game/UI/Menu/ServerBrowser/ServerDetails/SCR_ServerFullDialog.c:173
UpdateDetailIcons
scripts/Game/UI/Menu/ServerBrowser/ServerDetails/SCR_ServerFullDialog.c:339 Init
scripts/Game/UI/Menu/ServerBrowserMenuUI.c:2570
JoinProcess_OnJoinFail
Steps to reproduce:
1. Open the in-game Server Browser.
2. Select a server that is at maximum capacity (or has a join queue).
3. Attempt to join; wait through the queue until the join is processed.
4. When the join resolves with the server still full, the game reaches the SERVER_FULL join-fail path.
Expected result: A "Server is Full" dialog is shown and the player returns to the server browser.
Actual result: The game freezes on the connecting/loading screen (dark green background with the Arma Reforger logo) and then crashes to desktop. No "Server Full" message is ever displayed, because the dialog crashes during its own construction.
Reproducibility: Reproduced twice in a row on the same full server. Deterministic on the full-server join-fail path.
Suggested fix: Add a null check for m_wDetailIcon_CrossPlatform in SCR_ServerFullDialog.UpdateDetailIcons(), and/or verify the widget is bound in the SCR_ServerFullDialog layout so it resolves during Init().
Additional information: i used claude to generate a description since i do not trust myself to provide usable information :))
