When NBT data is entered into a /give command or a Pipez item filter GUI which causes the count variable to be unable to be parsed as an integer, the game will crash with java.lang.NumberFormatException: For input string: "___" with the invalid integer string filled in the blank, here:

To reproduce, type the following NBT data into a Pipez item filter GUI and pass in bigger_ae2:digital_singularity_fluid_storage_cell as the item to be filtered:

{"ae2:storage_cell_config_inv":[{"#":0L,"#t":"ae2:f",id:"water"}],"bigger_ae2:singularity_storage":{count:"___",key:{"#t":"ae2:f",id:"water"}}}

The game will then crash as described above.

Would it be possible to catch this error (invalid count) and gracefully handle it (by marking the cell invalid or clearing the contents) rather than crashing the game?

new release pushed, you can check it in curseforge in some minutes

Of course, I forgot to consider giving custom NBT
