Pondus inventory & TFMG Fix
by WarDreg
Pondus inventory & TFMG Fix is a NeoForge compatibility patch for 1.21.1 that stops a crash when Pondus Inventory queries certain TFMG inventories.
What it does
Pondus Inventory checks inventory capabilities on TFMG blocks, and the Blast Stove in particular, without always providing the side a request comes from. TFMG expects a valid direction in that context and otherwise throws a NullPointerException, which disconnects the player who is placing or interacting with the affected block. This mod adds a targeted patch to the inventory capability logic so that such requests are handled safely and Pondus Inventory can keep checking the supported inventories.
Normal TFMG inventory access is preserved whenever a valid direction is supplied. The patch runs only during the relevant inventory request, scanning loaded chunks and block entities on tick-based checks, so its performance cost stays small. It was created by WarDreg for the Warvior servers and modpack, and other server owners may use it in their own setups.
Both the server and the client need the mod, and the same version should be on each side. Server-side installation handles the affected capability on the server, while a client copy keeps the same request from failing there. Players without the mod on their client can still be disconnected, so matching versions matter. The mod is released under the MIT License and is not open source. Results on other versions are not something the author has covered, and the files cover only 1.21.1.
Key features
Blast Stove crash fix
Stops the NullPointerException that occurs when Pondus Inventory queries a TFMG Blast Stove without a block side.
Safe handling of side-less requests
Requests that arrive with no side are handled without crashing, so checks can continue.
Normal TFMG access kept
Inventory access with a valid direction behaves as before, so the patch changes only the failing case.
