Reason	Action
It is not possible to make parameter changes beyond the limit sizes.	Check the data in the preview window, increase the limit size, build the in-game preview data, and update the ACB in the game.
A waveform used as a stream cannot be replaced (the AWB file cannot be updated.)	You can replace a waveform by switching it to in-memory playback temporarily. Take note that this uses a lot more memory.
If the numbers of Categories and Voice Limit Groups increase, you must update the ACF as well.	You can avoid these updates by creating dummy Categories and Voice Limit Groups beforehand.

In both cases, you can reduce the update frequency by providing large data beforehand or increasing the maximum size allowed.
