@michoel I am finding it reproducible with admin 50% of the time, literally just refreshing the same customer payment form alternates between working and broken, totally inconsistent. I can see the below in console when it does wig out and have seen at least one other person mention the 'return Nanobar' causing error: VM1644 bootstrap.js:178 Uncaught Error: Mismatched anonymous define() module: function() { return Nanobar } at makeError (VM1639 NsRequire.js:252) at intakeDefines (VM1639 NsRequire.js:1325) at Object.localRequire [as require] (VM1639 NsRequire.js:1529) at requirejs (VM1639 NsRequire.js:1931) at global.require (VM1644 bootstrap.js:147) at c (VM1690 NLAPI.jsp__NS…locale=en_US.nlqs:1) at b (VM1690 NLAPI.jsp__NS…locale=en_US.nlqs:1) at page_init (custpymt.nl?entity=3663&currency=1:5609) at onload (custpymt.nl?entity=3663&currency=1:71)
