Generator bugged?

[Akumetsu]

Hi everyone, i guess it's not a problem that affects everyone because it's quite annoying when it happens.

When i pick a generator, it simply won't allow me to place it afterwards. I don't have the option to do so. I have it equiped in both hands but i can't drop it. When i change to another weapon it appears the message of "error" in the bottom right corner and the generator banishes. I thought maybe it was because i didnt read the magazine about generators, but i already read it and still happens. I have banished 3 generators at the moment. 

Im playing the IWBUMS beta. I don't know if this is a common error, but ty for your time anyway. 

 

Great game, btw, i enjoy it a lot.
