I'm running 1.3.0. and I presume that's the latest version? 
 
Anyway I'm not seeing any crashes but what I do find is that sometimes when you open the plugin window, the settings aren't showing what they really are. Like sometimes I will have the modulation set to "filter," and I can hear that the filter modulation is active, but when I open the window it's set to "phaser." And oftentimes I will find the delay time is set to something different in the GUI than the setting I can obviously hear. 

I've dropped Replika pretty much since I got Waves H-Delay on discount. Different beast than Replika but much more stable.

Yeah I have H-Delay too and use it lots but sometimes Replika is exactly what I need. I never use the silly diffusion mode but the phaser and filter modulation modes are good, and the "wide" is great in some scenarios.

I find this also when I alter settings, but I find if you minimise Replika and restore it nothing changes in the GUI display. So until this GUI bug is fixed I will use it in this way in future in projects.

Did the same here. H-Delay was just what I was looking for. Straightforward, stable and reliable.
