With the text based errors you have to get the sweet spot at your strength settings, cause you want the flux checkpoint you make his think. If you push the lora to hard into strength there is no room for own text creations with the cp. Also other loras that come with high strength may cause errors. That what I encountered.

@paskmoe you're right, it's much better with lora strength reduction, thanks

@Kalizz plz, what lora strength do you think is good, maintain the result and correct text
