SM v.1.11 is unstable.
e.g. ~50 % of my plugins are broken just by one of the latest sourcepawn commit. See
#613.
I updated the plugin. You can compile it by:
- downloading the latest version of plugin (v2.6.1).
- downloading the latest version of SM (at the moment v.1.11.0.6740)
For other plugins, wait for pushing the latest sourcepawn commit to the sourcemod.
