Description
- This is an extended and updated version of the Original Author GoD-Tony's plugin GameUI Crash Fix.
- This plugin fixes a rare crash caused by null activator when calling AcceptInput.
- Currently supported games:

• css
• hl2dm
• dods
• tf2
• l4d
• l4d2
• csgo
• insurgency

- Github Link

Requirement
- DHooks.

What's new
- New syntax updated.
- All offsets updated to latest.
- You can add keys in gamedata file to parse and prevent all entities that is possibly crashes the server for the reason related to null activator. e.g: filter_* entities with input "TestActivator" crashes the server if the activator is null. Same as entity "game_ui".

Why is this a bug?
- Please see the original post here

- When calling `CBaseEntity::AcceptInput`, there could be chance that the activator player was disconnected or the activator entity was destroyed, which will cause the activator pointer to be null to pass to `CBaseEntity::AcceptInput`. `CBaseEntity::AcceptInput` dose not perform any check for the null activator pointer, so once this null pointer is passed to the target input function and this function try to access the pointer, the game crashes. This could be existed in any source games and any entity that is related to this logic such as `game_ui`, `filter_* entity`, etc. - This plugin dynamic hooks the `CBaseEntity::AcceptInput` function with specific entity and checks if the activator pointer is null before calling the target input function. If the activator pointer is null, `CBaseEntity::AcceptInput` will be skipped and won't call the target input function.

Updated 1.2.1

- Use stringmap instead of arrylist. Thanks to Localia for reporting. - Hook entities on map start. Currently our target entities are created before on map start, it is way better than hooking them on created. Thanks to luoqixi for reporting.

The plugin is updated to 1.3 too, use the newer version I uploaded yesterday or downlaod it from github.
It added a config file, do not forget about this file.
I may forget about to upload the plugin itself, if it is then sorry about that.
