Is everything now working for you? Hoe did you fix it?
I tried capturing a Pokemon, but it crashed:
[Pokémon Essentials version 21.1]
[v21.1 Hotfixes 1.0.9]
Exception: ArgumentError
Message: wrong number of arguments (given 0, expected 1)
Backtrace:
[Raid Battles Hotfixes] [003] Pokemon...
I installed this because I encountered a crash after catching a Pokemon. But now after installing, it doesn't crash anymore, but also doesn't save the Pokemon. If I catch one, it registers as caught but is neither in the party nor the PC.
