To expand:
Constant issues with backend config not actually being saved, across different files at different times. Nothing to do with Eco itself updating or anything, just completely at random.
Near zero modding (full Clays only, no ability to change files of it) with no ability to add more mods when requested, even when they're entirely non-DLL mods.
Poor near zero refund policy even when things like this present themselves. Only option is to go via Paypal or CC.
Donations via Clanpay (community payment system) 100% non-refundable, even when they've not been used yet and won't be used for a considerable amount of time.
Tickets being closed with no response, both due to system error and confirmed by staff.
